Sony strategic management and leadership Essay Example | Topics and Well Written Essays - 2750 words
Sony strategic management and leadership - Essay Example According to Sonyââ¬â¢s C.E.O, the companyââ¬â¢s mission is to challenge the designers, producers and engineers in order to improve their software and hardware and eventually advance its differentiation process towards its competition (Badawy, 2009). Sony has renowned heritage of creativeness and innovativeness. Sony boasts of having products in the electronic, games, entertainment, and still participate in the provision of financial service sectors (Flugge, 2008). In this regard, this essay will delve on a critical analysis of Sonyââ¬â¢s strategic management and leadership. More so, it will analyze Sonyââ¬â¢s marketing advantage with supportive evidence. (1) - Sony corporation success Traditionally, Sony was known as a great innovator that managed to transform the entire categories of electronics with unique products like the PlayStation game console and Walkman music player. More so, Sony was in a position to command premium prices for its top-quality products (Gao, Men g, Steve, 2008). Therefore, Sony did not only the electronic industry but it also changed the world because Sony brought about smaller portable devices to the market, which is contrary to the old electronic devices that were bulky and inefficient. Sony has tremendously grown in market share and profitability (Ajami, 2006). Numerous evidence portrays this growth, for instance in the year 2006, Sony topped a Harris poll as the best brand which was the seventh time consecutively, while dell and coca- cola took the second and third positions. In 2004, Forbes ranked Sony as the 72nd largest company in the world. Recently, in January 2013, Sony scooped the So-net Entertainment Corporation award. According to Interbrand Top 100 Global Brand 2011, Sony emerged position thirty-six among other a hundred brands (Anonymous 2012). Prior to successful market share, Sony boasts of diverse and effective employees who in the year 2011 they were ranging at 168,200. On February 25, 2013, Sony sold a 6 .0% stake of a 55.8%-owned subsidiary (Minato-Ku, 2013). Factors that have contributed to Sonyââ¬â¢s success Sonyââ¬â¢s main contributor to its success is its unique variety of brands that match up the latest modern world. The company manufactures television screens and projector, cameras, home theatre systems, computer hardware, mobile phones, and car entertainment devices (Plunkett, 2008). Additionally, Sony manufactures home recording devices, storage media, and charging devices (Nargundkar, 2006). Ideally, Sony has further divided some of its products into other sub categories especially for the television products. This has made the company able to service its market through the innovation of tailor made products that suit their various clients. These customers include households, offices, and public gatherings. Hence, Sonyââ¬â¢s success comes from due to the ability of the company to produce products that are able to meet the needs of their customers without financial constraints as their quality dictates the price (Ferrell & Hartline, 2011). Moreover, Sony also uses strategic marketing skills to the improvement in sales capacity. These marketing strategies include market mix, online marketing among many others. Ideally, Sony has managed to use its favorable public rapport to maintain significant relations with its employees, consumers and other relevant stakeholders (Shajahan, 2004). The use of its

Political Aspects of Wireless Electricity Essay Example for Free
Political Aspects of Wireless Electricity Essay It is no secret that politics plays a big role when it comes to the introduction of the wireless electricity. Some parties are for it, as it can allow for slightly greener ways of powering devices, new jobs, and easier access. But others are against it, seeing the change as a threat to old ways of doing things, as well as a way for people to access electricity for free. Though wireless transmissions and the idea of wireless electricity have existed for quite some time, the actual possibility of creating usable, accessible wireless electricity is just now starting to become a reality. With wireless electricity looming on the horizon, more and more politicians, civilians, and companies are beginning to stand behind the idea; but that has not always been the case. Politics first began working their way into wireless electricity in 1905, when J. P. Morgan pulled all of his funding from Nikola Teslaââ¬â¢s Wardenclyffe Tower project when he erroneously began to believe that it could lead to free electricity for all (Haliburton, 2006). It is that same type of thinking that has helped to keep wireless electricity out of the mainstream for so long. However, information and general knowledge about wireless electricity has come far, and that type of thinking is quickly disappearing. With the recent surge of environmental and financial awareness, people are quickly beginning to gravitate towards the idea of wireless electricity. Even power companies are getting behind the idea, seeing a way to expand their business. Though the idea of wireless electricity has just begun to reemerge, it will quickly become a hot political topic, just as other forms of alternative energy have. The question is this: Will the general public and politicians continue to gravitate towards this new concept? And if they do, how long will it be until wireless electricity becomes the norm?

Free Rider Problem Essay -- essays research papers
The Free Rider Problem à à à à à The free rider issue has become one of the most serious economic issues today. The free rider is a lazy type person who wants the benefits that others bring in without having to do the work. The free rider typically takes advantage of a public good. Living in a civilized society presents many opportunities for free riding, which we have yet to find a way to control. Economists regard the possibility for free riding as a problem for the free market, which usually leads to government intervention. Government intervention is not generally needed in a free market society but in this case if there were no government intervention this problem would not find a solution. à à à à à The free-rider issue is often seen as a serious problem because of the assumption that a free rider's best self-interest is that they interact with others by force and fraud. If they can get away with the fraud and begin to gain the benefits of others they have reached their first goal. Their next goal is to make some good money or get credit for someone else's hard work before they get caught. Then they get out and are long gone by the time anyone notices. Life in a civilized society allows each of us the opportunity to enjoy the benefits of the work of people with productive ability far greater than our own, but what happens when people begin doing this? They get used to not having to do much work and become lazy. In some cases people look at welfare in this way. If a person is able to get a good job and chooses not to, but instead, to live on our government, this would be considered free riding. This causes a fluctuation in our market and it can have a negative effect. When the benefits go away people do not want to go back to work and eventually will loose their jobs or quit and become a true free rider. Clearly there is an essential difference between cases in which one can't contribute to the benefits one enjoys and cases in which one chooses not to make a contribution that is within one's power. But apart from this distinction, we can differentiate between harmless free riding and the worthless free riding. The free rider wants anything he can get for free and will think nothing of it if he can get away with it. Free riders take advantage of public goods without having to contribute to them. For example, if s... ...o make up the difference. This difference we have to make up is usually a higher tax. In raising the tax the price of the good goes up and when price goes up demand tends to go down. As the demand keeps falling and the price keeps rising the product usually ends up off the market and filing a chapter eleven. It typically does not go that far but this is an example of what could happen. A free market is a privilege to have and it is a shame people have to take advantage of it because they do not feel the need to work hard or to go out of their way to do something for someone else. à à à à à The free rider is a menace in our society and we do not need to let him take our money and put it to his use. We have found ways such as government intervention and price lids to help control the problem but we have yet to find a solution. Once a solution is found we will have fewer worries and possibly a true free market. These are very difficult problems to stop and may never be stopped. It will take a long period of time to begin the process to bring it to an end, but it will be nice to maybe some day have a true free market without the problem of a free rider.

A Futile Task- the Catcher in the Rye Essay
The teenager stands on a hill in complete solitude, watching the nearby football game, and contemplating if he should say a final farewell to the school. Ambivalent, the melancholy teenager leaves himself in a confused and vulnerable position to the lonely and corrupt reality of the world. In an attempt to endure the vices that alter the blissful spirit, he feels the need to make things right by saving what little recognizable evidence of purity that the world has not already desecrated. All throughout the novel The Catcher in the Rye, author J. D. Salinger establishes Holdenââ¬â¢s bizarre attraction toward particular places, objects, and experiences, past and present. The author concurrently sets out the subtle, tender concern that Holden has for the preservation of innocence and where life will ultimately end up. At essential points in the plot, Salinger embodies these two motifs, which metaphorically represent each other, in order to uncover the true sadness that lurks in an abandoned Holden. By doing this, the author reveals the greater theme that unlike artifacts of history, constrained the human spirit would severely stunt any opportunity of development for people. Salinger constantly highlights the motif of Holdenââ¬â¢s endeavors to preserve innocence from being tainted by corruption. The author first presents this through the objects that Holden develops a bond with. To demonstrate that bond, Salinger produces a scene in which Holden visits his old teacher, Mr. Spencer, one of the few concerned about the boy. The teacher asks Holden to read his paper about Egyptian mummifying aloud. Salinger first demonstrates Holdenââ¬â¢s obsession for the preservation of life when Holden divulges that ââ¬Å"Modern science would still like to know what the secret ingredients were that the Egyptians used when they wrapped up dead people so that their faces would not rot for innumerable centuriesâ⬠(Salinger 16). Implying the deep interest that Holden possesses for this subject, Salinger underscores that the teenager may have experienced a harrowing event relating to the matter. Because Holden would still dearly like to know the ââ¬Å"secretâ⬠of maintaining life in such a state, the author also exposes Holdenââ¬â¢s unawareness of the topic altogether. Leaving Holden in an unaware state, the author then inserts the minor motif of Holdenââ¬â¢s younger brotherââ¬â¢s baseball mitt to clear the confusion. When asked to write a composition for a classmate, of all the topics Holden decides to write about, the nostalgic adolescent distinguishes his younger brotherââ¬â¢s baseball mitt. With this sacred object, Salinger links it to Holdenââ¬â¢s goal for conserving the unharmed and the aesthetic, as the glove had poems scribed all over it in ink. The author represents the ink as the permanence in which the item endures. Similar to the beloved baseball mitt, Holden finds solidity in a Little Shirley Beans record that he purchases. Identifying the song eternally preserved on the record, the writer elucidates that Holden still preserves things in the state that they are left, never allowing them to change. Salinger also represents Holdenââ¬â¢s remembrance of the innocence of childhood, the record reminding him of that period. In addition to the revered objects, the author exhibits a pattern in Holdenââ¬â¢s experiences and anecdotes that motivate Holden in the direction of making events like those last for an eternity. One of Holdenââ¬â¢s recollections that Salinger touches on briefly involves Holden playing checkers with a childhood friend, Jane Gallagher. At one point in the game, Jane cries, and sensing this, Holden drives his efforts to console with her, kissing her all over her face, avoiding her mouth. Symbolizing the need to protect Jane and her virginity, the author portrays Holden comforting her instead of violating her, revealing the tender empathy that Holden possesses. Prior to reflecting this memory, Holden underwent an instance of rejection at a bar, and seeing what little empathy people have, Holden tries to remember a positive memory to keep his motivation alive. One of Holdenââ¬â¢s fondest memories stems from the remembrance of his younger brother. When given time to ruminate upon his past, Allie stands out as the ideal brother that Holden would never find in any other person. Salinger distinguishes Allie as ââ¬Å"terrifically intelligentâ⬠and that ââ¬Å"he was also the nicestâ⬠¦ he never got mad at anybody. People with red hair are supposed to get mad very easily, but Allie never did, and he had very red hairâ⬠(Salinger 50). Portraying Allie as the epitome of childhood innocence, the author juxtaposes this to Holdenââ¬â¢s thoughts of preserving purity. Because his sibling passed away at an extremely young age, Holdenââ¬â¢s sole coping strategy involves the thought of bringing back his brother, thinking that someone as magnanimous as Allie deserves to live on. Despite Holdenââ¬â¢s naive point of view toward what troubles him, he finally begins to subtly realize something about his brother. Salinger weaves a scene of Holden conversing with Phoebe, his younger sister, and the teenager mentions that he loves Allie, thinking that he still exists. Following Phoebeââ¬â¢s comment that Allie is dead, Holden refuses to accept and reveals that ââ¬Å"Just because somebodyââ¬â¢s dead, you donââ¬â¢t just stop liking them, for Godââ¬â¢s sakeââ¬âespecially if they were about a thousand times nicer than the people you know thatââ¬â¢re alive an allâ⬠(Salinger 223). Salinger highlights a rare moment: someone offering guidance to Holden, accepting that he is stuck. By displaying Holden touching upon Allie, Salinger expresses the adolescent beginning to address the connection with Allie. However, Holden still possesses the unawareness to come to terms with this. Salinger effectively amplifies the essence of Holdenââ¬â¢s being in a thought of the teenager. The author illustrates a dream of Holden desiring to catch children who accidentally fall off the ledge of a cliff in the rye field, the adolescent defining himself as a catcher in the rye. The author resembles Holden as a selfless martyr in this thought, leaving Holden in bliss that he can save people if they fall; the author makes clear that, for Holden, danger should be avoided by all means and at all costs. Salinger stems the implication from Holdenââ¬â¢s own dealings with losses Perhaps the most important category that Holden associates with conservation and longing consists of the places that he visits. One of the first locations that Salinger introduces pertains to the museum, a site of never changing exhibits. The boy favors that all the displays stay the way they are and that things are kept in fixed positions. By symbolizing the museum as a place where nothing changes, Salinger mirrors the setting to Holdenââ¬â¢s opposition to growing up and change. Salinger initiates the beginning of a epiphany for Holden when the teenager travels to his old elementary school to meet with Phoebe. The writer describes the school as familiar to Holden While appearing to give up hope on the world, Holden sees yet another instance of chicanery. The author depicts an obscenity on the wall that appalls Holden, and in the act he makes of rubbing it out, Salinger reiterates Holden as a savior figure and that combating all of evil can be accomplished. The author furthers the learning experience for Holden when the teenager returns to the museum. Although feeling tranquil while all alone in one of the showcases, Holden observes yet another contemptible obscenity, defacing one of the glass cases. By repeating the obscenity for Holden, Salinger starts to affirm in Holden that he cannot keep everything clean and pure but must accept events like these once in a while. Finally pivoting Holdenââ¬â¢s vague realization to the last crucial place, Salinger fleshes out the epiphany. Accompanied by phoebe, Holden views one of the carousels nearby, his attraction to it brought on by the fact that the ride always plays the same song. Holden again clings to a familiar tangent and what comforts him. Yet, the teenager watches Phoebe go around on the carousel and sees her and other children trying to grab for the gold ring. Salinger depicts Holden as ââ¬Å"afraid that sheââ¬â¢d fall offâ⬠but he does not react, as Holden realizes that ââ¬Å"If they fall off, they fall off, but itââ¬â¢s bad if you say anything to themâ⬠(Salinger 274). Paralleling and directing opportunity and danger close together, Salinger enables acceptance in Holden that if people stay the same way, there leaves no room for development, thus rendering them static, strayed from the dynamics of change, and this time, Holden does not deny Phoebe or himself the opportunity to mature.

Organizational Communications Analysis Womenââ¬â¢s Resource Center at Norman, Oklahoma
The Womenââ¬â¢s Resource Center was originally started in 1973 and 1974 during the winter. It was originally started by a graduate student who wanted to assist women who were in transition points in the life. This organization could not function without effective communication and to analyze the communication strategies of the organization can provide helpful information that could further improve them. This included those women who were looking for employment as well as women who wanted to return to school. Since its opening the center has developed many programs and services (ââ¬Å"History.. â⬠1). There are many programs available at the Womenââ¬â¢s Resource Center and these include WRC Victims of Domestic Violence Shelter (providing safe temporary housing to victims of domestic violence and their children); Rape Response Team (trained volunteers who are available to meet with rape victims at the ER); counseling (specialized for victims of sexual assault or domestic abuse); WRC Education Program (offers staff that speak in a variety of places for about topics having to deal with domestic violence, date rape, healthy relationships and other topics); Childrenââ¬â¢s Program (groups that focus on letting children express their emotions and feelings); Court Advocacy (court advocates to help women through the legal system); and WRC Cells (a program to offer victims cell phones at no cost in case of an emergency) (ââ¬Å"Programs.. â⬠1-2). There are also some training workshops. The main one is SANE (Sexual Assault Nurse Examiner) Volunteer Training, a specialized trainin g for nurses to learn how to do forensic rape test kits (ââ¬Å"Trainingâ⬠¦Ã¢â¬ 1). Effective communication is one of those things that are important to how well an organization is run. The Womenââ¬â¢s Resource Center in Norman, Oklahoma has a lot of strengths in their communications. They do a good job of training both their staff and their volunteers. They work with their staff on issues about communications and knowing when to talk and when to be able to allow others to talk as they are dealing with people in very difficult situations. They learn how to effectively communicate for the situations that they are in where there is a high risk to the women that they are talking to. This means that there is a lot of training put into the idea of communications for this organization. Their main strength in communication is the overall ability to communicate effectively with those who are in a tough situation. The reason that this works so well is that there is a great deal of things in the communication process (Lee 2). Knowing the communication process can greatly help how communications are for people. According to Lass wellââ¬â¢s model of communication there needs to be an effect for the communication to take place. What this is saying is that what is being communicated needs to have a point and a direction. In this communication process the organization is trying to point out that women deserve respect and self assurance (Lee 3). The idea of effective communication for change is something that this organization does well. The organization has made a lot of changes in the past both the long term past and the recent past. These changes are effectively communicated if three major components are available in the strategy. This study by Larkin and Larkin stated: ââ¬Å"Communicate only facts; stop communicating values. Communicate face to face; do not rely on videos, publications or large scale meetings. And target front line supervisors; do not let executives introduce the change to frontline employees. â⬠This is an example of the effective things that Womenââ¬â¢s Resource Center communicates as they use a strategy that shows that each level learns new things (Cheney 330). Some of the negative things that are done at the Womenââ¬â¢s Resource Center with communications are that the trainings are not available to the public for information. They do offer some training seminars but in the end the trainings are not available as a program on the intense level. The communication process is not as well done in advertisement or getting the word out about the programs that are available. Another area that shows weakness in communication is the organization. There is not a strong organization in this company and there are many different people volunteering and/or working for the agency. Some of the areas that could use improvement include the areas of communication about the organization and throughout the organizations volunteers and employees. This meaning that they all could use better communication to communicate between one another. The idea as stated in the same study as above is that there is sometimes little credibility to the values could be one of the communication problems in this area as it would be a problem in communicating and that the upper management and board of directors have not had a very clear vision with the Womenââ¬â¢s Resource Center as many things have changed about their main values and ideas since the creation of the center which could cause some confusion (Cheney 330-333). A second area that has caused some problems with communications in the organization has been a lack of employed resources. This means that there are a lot of volunteers who might not have the same standards to communicating needs as regular full time or even part time employees would have. In order to effectively improve these areas there would have to be a system set up which would give both volunteers and employees a chance to express their feelings and ideas without the fear of being persecuted and with the idea that anyone who is involved has an opinion that matters. The idea that communication is a big part of leadership and how well leadership runs is based on the leaderââ¬â¢s ability to communicate effectively. In this case this would be an area for needed improvement (Cheney 205-206). There are many areas where improvements could be made in the communication processes with the Womenââ¬â¢s Resource Center. Some of these areas are that the management could be give better support to all of the volunteers and employees alike. Another thing that could happen is that those who are involved would be able to voice their opinions and give a case for care. They would be able to effectively communicate their needs in a process that would be pre-developed by management as it would be something that they could use on a regular basis. This means that they would be able to better manage their communications needs by effectively learning how to resolve issues and discuss issues with proper communications. The theory of Schramm on communication and the idea that overlapping boundaries and experiences make for easier communications is key in the field and services that the Womenââ¬â¢s Resource Center is providing. It is in this process that these workers and volunteers would be able to communicate better with the clientele based on whether or not they had shared the same or similar experiences in their past (Lee 3-4). The strengths and weaknesses for this organization were apparent when reading over the press releases and other information available about the organization. Also the writer observed the communication aspects while working for the organization prior to returning to graduate school. This was observed through being a part of the organizationââ¬â¢s training and programs. It was also observed through understanding information about the programs and how they are communicated to the public. Being able to effectively communicate is very important in the field of social work and for social service agencies. The one area where communication is well done is between the staff and the victims that come in for services as the training programs in this area are very good. Therefore their main strength is being able to communicate well to women in tough situations. The Womenââ¬â¢s Resource Center is an organization that needs to have superior communication skills in order to deal with the problems that are being affected on a regular basis through their organization as they readily do not know what is going on and sometimes are in need of being able to communicate in a more effective manner. One of the main problems has been a lack of communications through the numerous volunteers and employees and in the end it has been a cause for some communication gaps. The main thing that can be done to improve the status of these things is for there to be a better communications system in place in general for the organization. This means that the organization would have better communication between the management and the employees and volunteers. Some of these communication gaps are what are causing the down fall for this organization and are some of the leading causes of the overall conflict that is experienced within the organization. There are always going to be ââ¬Å"inherent challengesâ⬠when discussing communication and workplace environments (Messersmith 1). In the end communication is very important in all areas of life and when there is effective communications in some areas it lends hope to the idea that there could be effective communications in all areas of an organization. While analyzing communications for the Womenââ¬â¢s Resource Center it is no wonder that there are many different types of communication used and it is no wonder that there are some needs for improvement. Most of the need for improvement falls on the overall board of directors and their ability to create a clear plan for what they want and what is going on within the organization. Without this they are not able to give back to the organization what is needed in order to be effective in their management and other skills. So what is needed is for the organization to work on their being able to communicate better within the organization through a set system in place for communications. This would mean that no matter when the individual was seen and whom she was seen by the whole organization would be able to help her in the future. Preparing basic short case studies and sharing them during a team meeting would be one way that this could be possible. Part of this is also being open about the organizationââ¬â¢s needs. ââ¬Å"Employees need to be aware of the challenges the company is facing so that they can do their part to help. â⬠A second thing that needs to be done better is the communications that are given between the organization and the community, meaning that the community would be better informed in the future (Basili 2).

Measuring the specific heat capacity of water Essays
Measuring the specific heat capacity of water Essays Measuring the specific heat capacity of water Paper Measuring the specific heat capacity of water Paper Introduction The Specific Heat Capacity of any substance can be defined as the amount of energy needed to raise 1kg of the substance by 1i c. Its found by using the following formula: C = Q / (M x ? ?) Where (C) represents the SPHC; (Q) the energy needed or given out in joules; (M) is the mass of the substance calculated in kilograms and ? ? represents the change in temperature in either i C or Kelvin. Aim The aim of the experiment is to determine the Specific Heat Capacity of any liquid, but in our case Water. Hypothesis I think that we will obtain a close number to the exact Specific Heat Capacity known as 4200 J/Kgi C. , though it will not be 100 accurate because some heat will be lost, leading to possible errors in data. I dont think we can insulate 100% with the following calorimeter at school, thus it might gain or release energy causing in-accuracy. Additionally I think that the change of temperature will be constant throughout the experiment, because the amount of energy given will always stay the same. I also believe the temperature will rise proportional to time, this is because as more time is expanded, the molecules receive more heat, according to the Kinetic Theory, the molecules become more active, and start to move rapidly increasing collision rate. Thus more the time, the higher the temperature will be until a certain point. This is the boiling point, and this is when the molecules have reached the maximum point, and are on the point of transforming into another state of form gaseous. Apparatus A Calorimeter A Thermometer A Electric Weighing Scale. A Power Pack d 1. An empty calorimeter is weighed. The liquid under test is then poured in the calorimeter and reweighed. The Mass m of the liquid is found. 2. An immersion heater and a thermometer are placed in the calorimeter 3. The initial temperature ? ? 1 of the liquid is recorded. 4. The liquid is heated for a time t seconds. The stirrer is used to maintain a uniform temperature throughout the liquid. The lid minimizes heat losses by convection. 5. Record the temperature after every two minutes and plot it in the table below. 6. The final temperature ? ? 2 is noted and the changed in temperature ? ? after time t is found7. Record the results in the table below Precautions 1. To properly place the lid, otherwise heat lose might increase, to minimize heat loss as much possible using insulation. 2. To maintain uniform temperature make sure to keep stirring the calorimeter. 3. Make sure to keep constant energy supply by heater 12V. Variables Independent Is the power heating the up the water. This is because if you change the power, then the change in temperature will also change proportionally. So you have to keep it constant throughout, otherwise this might lead to un-reliable data. To manipulate you could change the power, by increasing the current or the volts. So you could change the current from 12V, to 16V, which would change the power. But this has to be done at the start of the experiment, and then kept constant throughout. Dependent This is the change in temperature, as this is dependent on the power supplied to the heater, if changed then the change in temperature will also change. To manipulate, you will have to change the Independent variable. Controlled This is the mass of the water, the time intervals and the power. These have to be kept constant, or otherwise it wont be a fair test. The mass of the water is kept at 0. 425 kg, 120 second time intervals and 12W power supply. To manipulate you could increase the mass by 0. 010 kg, or increase the power supply to 16W, or even increase or decrease the time intervals to either 300 second or 30 seconds. But the changes have to be kept constant otherwise. Results Time / Seconds Temperature / (? ) Change in temperature. E = the power in watts Q = the energy in joules T = time in seconds 12 x 0. joules Now to find the Specific Heat capacity we have to go back to the original formula, and deduce these finding into it. Re-arrange the formula C Conclusion From my calculation and results I have obtained the Specific Heat Capacity of water to be 4320 j/kgi C for this practical. Now I can argue that this is not a 100% accurate experiment as the scientifically defined Specific Heat Capacity of water is found to be 4200 j/kgi C. There is a difference of 1320 j/kgi C, from my results and the initial value; but I used two different ways to calculate the answer. I used the formula, which gives 4320 j/kgi C, but then I also used the gradient which in result gave me a more accurate answer of 4235 j/kgi C. As you can see the gradient gives a much more accurate answer, this is because when you use the method of calculating the sphc, by subtracting the final temperature by the initial temperature, you only base your calculation of two sets of data. This is unreliable, because if one of them proves to be inaccurate, then this impacts the answer proportionally. The gradient method is more accurate, because you are taking the data from the line of best fit, which allows you to predict the value of one variable based on a value of the other; avoiding erroneous sets of data. Using the gradient method I got an answer of 4235j/kgi C, which is very close to the initial value of Specific Heat Capacity of Water. There is a difference of only 35j/kgi C, and a difference of 85j/kgi C from the calculations using the other method. So why isnt my answer identical to the genuine calculation? Well this can be caused by many reasons, one is that the calorimeter partially absorbed some of the heat which in turn meant, that it needed more energy to raise the temperature of the water, as the particles had less energy due to heat loss. Another reason could be because it was insulated 100%, which meant that it lost some heat to the air, which again meant that the particles didnt have as much energy so it needed more. Though this reasons will only slightly affect the answer, as we didnt not perform the experiment at a very high temperature. In my hypothesis I stated that my answer for the specific heat capacity will differ slightly from the original, and I was right, but I also stated that the change in temperature will be constant, and that the temperature will rise uniformly. Theoretically I should be right, but from my results you can see that the change in temperature wasnt constant. This is because I didnt stir, the calorimeter enough and persistently. This would have made the particles in the water move more so the temperature would have then increased. The more stirring that was done could have allowed the temperature to increase at a fully uniform level. And I think that the main reason why my results of the specific heat capacity doesnt exactly equal 4200 j/kgi C. Evaluation I think that I was very close to the precise specific heat capacity of water. With a difference of only 35j/kgi C I think that there are variables, which cannot be controlled 100%. But I think I could have improved this experiment. I think next time I could take a wider range of data, for the temperatures. This means to repeat the experiment numerous times. This will allow me to have more accurate data. Also I think I should keep the stirring of the water more persistent next time. I could either, have a plan of something like, stirring for 2 minutes, and then stopping for an minute etc. Or I could persistently keep on stirring through the whole experiment; this will allow the particles to move around the beaker more, making it a fairer test. Also I could increase the power supplied to the calorimeter, which would allow me to analyze the relationship at higher temperatures, and also more modern equipment. All these factors could be improved next time, hopefully giving me even accurate results. 1 Appendix 1 2 See Graph Show preview only The above preview is unformatted text This student written piece of work is one of many that can be found in our GCSE Electricity and Magnetism section.
