Specific Heat Capacity of Water (DCP and CE) free essay sample

The uncertainty in time interval is taken 0.1s because the stopwatch we used had a least count of 0.1 s and was digital. Here, uncertainty in temperature is 0.5 °C because the least count of the thermometer was 1 °C and it was an analog thermometer. So uncertainty is half the least count. Now, the average temperature was calculated by taking the sum of the four temperature values for a specific time and dividing the sum by 4. The uncertainty in temperature was calculated by finding the difference between the maximum value and the minimum value and then dividing it by 2. Sample Calculations: 1. Average temperature = (27+28+28+27)/4 = 27.5 = 28 °C 2. Uncertainty in temperature = (Max-Min)/2 = (28-27)/2 = 0.5 = 1 °C Table 2: Table showing average temperature and uncertainty in this average with corresponding time Time/s  ± 0.1 s Average temperature/ °C Uncertainty in temperature/ °C The relatively low percentage uncertainty and discrepancy show that the experiment was very precise and accurate. This means that both random and systematic errors were very low.

According to the hypothesis, the graph was supposed to be a straight line which passes through the origin. But here, we can see a y-intercept. This means that even when the time was zero, there was a certain temperature (23.8 °C). Here, we know that this is the temperature of the water according to the surrounding when the heating process had not started. And the value from the graph (23.8 °C) is quite close to the actual observed value during the experiment (26 °C). The range of the y-intercept also includes a value that can be explained with the same explanation. ERROR EVALUATION As mentioned above, the low percentage uncertainty and discrepancy shows that the errors are not very significant. The errors are listed below along with improvements. Random errors: 1. Difficulty in measuring temperature – Measuring the temperature while it was rising was a little tricky as both the time and the temperature had to be observed simultaneously. This was, however, made easier by having two people in the team. 2. Temperature of water is not same throughout the beaker – This means that the water heating does not take place uniformly, so the relative position of the heater and the thermometer affects the values of temperature. Using a heater from the bottom and keeping the thermometer at a fixed height from the bottom would reduce this error. 3. Least count of thermometer – The thermometer we used had a least count of 1 °C which is quite high. Using a temperature probe would give us more precise values. Systematic errors: 1. Time taken to heat the heater itself – The heater itself took some time to heat up which could be the cause for the outlier in the graph. 2. Heat lost to surroundings – Heat is lost to the atmosphere as well as the beaker while heating. This constantly decreases the amount of energy supplied, resulting in a lower value for ‘c’. Using a calorimeter with a lid would reduce this. 3. The beaker was kept open – This resulted in evaporation of water and, thus, a decrease in the volume of water. This would result in a decrease in the mass and therefore increase the value of ‘c’. Use of a lid to cover the beaker would help control this error. 4. The power of heater was not measured – We assumed the power mentioned in the packaging to be absolutely true and without uncertainties, but this might not be true. If we measured these ourselves, we would also know the uncertainties and therefore, get a more accurate value. 5. Power of heater changes with change in temperature – A change in temperature results in a change in the resistance of the heating coil and therefore, the power changes as well. 6. Use of tap water – Tap water contains many impurities, which affects water’s specific heat capacity. Using distilled water would help reduce this. 7. Beaker and heater were not cooled down completely after each trial – The beaker and the heater were rinsed a few times very briefly. This means that they were not cooled down properly and therefore, that provided certain energy to the water. This decreases the value of ‘c’. 8. The volume of water was measured instead of the mass – The density of water was assumed to be 1 gcm-3, which might not be true because of the impurities in tap water. Directly measuring the mass would have given better results. From these, the most significant errors would be the heat lost to the surroundings and the evaporation in the process. Controlling these two would give a more accurate result.

The Company should adopt leadership and management approaches that motivate and encourage employees towards attainment of the organizations goals (Bass Riggio, 2008). In addition, the leadership and management styles should encourage communication between the employees and senior management and remove vices such as discrimination that tend to discourage employees’ work performances. Moreover, the leadership style should focus on creating positive change among employees through encouraging creativity and innovativeness in solving the problems facing the organization. The other plan for the organization should focus on creating positive relationship with the customers. Focusing on positive relationship with the customers entails generating services with additional value that satisfy clients beyond their expectations. Ensuring that the services provided are beyond the customers’ expectations will increase the firm’s clients’ base (Bangs, 2002). Focusing on customers will also ensure increased sales and revenue, which is critical for the growth and development of the firm.

Although random sampling is quick and convenient method for selecting the participants, the researcher is free to select the participants who are accessible and convenient though not necessarily representative. Every respondent will be informed about voluntary participation and the level of confidentiality given to the information provided. In fact, the researcher will request the participants not to indicate their names and other personal or confidential information on the questionnaires to increase the chances of participation. Besides, the level of participation will be handled by informing the participants about the significance of the study. All these measures will assist in reducing non-response rates. Data analysis Given the nature of the research study to be conducted, descriptive statistics will be used to analyze data. In addition, data will be edited to ensure logical completeness and response consistency. Besides, the collected research information will be analyzed q ualitatively and quantitatively. The qualitative data will be analyzed using logical analysis and content analysis techniques. Regression analysis will be conducted to determine the relationship between the factors being investigated. The transactional and transformational style of leadership and the best leadership style for Bharat Airways Transactional leadership Transactional leadership focuses on the interactions between the top management and employees. In fact, in transactional leadership styles, rewards and punishments are used as a form of motivation. Rewards are in various forms and are provided to employees with increased performances and loyalty. Transactional leadership styles are effective in situations where increased performance is the major objective of the organization (Bass Riggio, 2008). In addition, transactional leadership works better in the circumstances where the problems can clearly be observed and simple. In other words, employees understand the limit and the consequences of their actions.Advertising Looking for case study on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More One of the major disadvantages of the form of leadership is that employees are aligned to the organizations requirements. In other words, transactional leadership does not encourage innovativeness and creativity in solving the organizational issues (Bass Riggio, 2008). In other words, the leadership style does not allow employees to be creative and innovative in getting solutions to the problems. Employees do not contribute creatively and innovatively in getting solutions affecting their work processes. The leadership style is not suitable in complex organizations where creativity and innovativeness remains critical in the attainment of goals and objectives. Most importantly, under complex situations where employees’ contribution is emphasized, transactional leadership is not the best approach (Bass Riggio, 2008). Essentially, Bharat Airways cannon apply transactional leadership style in managing employees given the complexity of the organization and the current situation. Transformational leadership Transformational leadership is characterized by its inspirational nature and positive changes it creates in an organization. Transformational leadership takes into consideration the concerns of employees and is focused on encouraging employees to achieve the goals of the organization. In fact, transformational leadership is geared towards creating positive change among employees. Moreover, in transformational leadership style, the members of the team are encouraged to attain the desired results on the assigned tasks. Further, leaders impart the vision of the group and take into consideration the members’ contribution in the attainment of the results. Besides, Transformational leaders have greater vision as well as inspirational characteristics, which is applied to motivate and change the expectations as well as perceptions of employees to work towards the desired goals and outcome. Given the circumstances in Bharat Airways, transformational leaders hip style is the best employees’ management approach. The reason is that employees of Bharat Airways need to be encouraged, motivated and inspired towards attaining the goals of the organization. In addition, Bharat Airways need visionary leaders to inspire and motivate employees towards attaining the desired outcome. Such characteristics are found in the transformational leadership style. The immediate steps to improve the situation of the organization The first step is to create a vision for the organization and formulate clear objectives that are achievable and measurable. Once the vision, mission and objectives have been formulated, a clear strategy outlining the steps on how the organization’s goals will be attained is then established. The vision, goals, and strategies are communicated to the employees as well as other stakeholders of the organization. Imparting the vision, goals and strategies will ensure that all stakeholders are involved in the attainment of t he organization’s goals. The second step is to come up with strategies that will ensure a change in the management of employees and leadership styles. The new management style will remove obstacles that alienate employees from work processes. The leadership style should encourage employees towards attaining the desired outcome.

Moreover, the firm will aspire to introduce creative airline services and products in the airways market to establish its brand name. The products and services will be improved to suit the customer needs and bring convenience, a mixture of value and quali ty. Pricing strategies As expected, quality and increased value will attract high prices (Constantinides, 2006). Most of the Bharat Airways services are middle-high priced. However, the firm offer services that target all clients including high-end, middle and low classed travelling customers. The high-quality high-prices strategy will be applied particularly to outperform other airline competitors. In addition, the pricing strategy will be aimed at widening the spectrum of customers being targeted. In fact, the firm has been targeting customers at all levels. As such as, commissions or discounted prices will be offered to clients who use airlines often. Nevertheless, with entry of more competitors in the airline industry, Bharat Airways will widen its scope and capture the middle, high, and low-income clientele. Bharat Airways will also offer different prices to the clients including apex fares, low cost, cheap value, premium and value for money. Placing strategies Bharat Airways w ill adopt the business to customer distribution channel in order to directly deal with its customers. Direct interaction with customers will lead to the development of products and services that suit the customers’ needs. Moreover, direct sales of products and services will lead to prolonged market share. However, the routes of the airline around the world are still limited given that the firm is centrally placed. Therefore, Bharat Airways will expand its operation routes to reach all sorts of customers. The placement strategies will include offering affiliated services with different companies, using travelling or tour operator agencies, as well as making the twenty-four hours online reservation systems available to all clients.

Harlem Renaissance Poets Essay Example | Topics and Well Written Essays - 1000 words

Harlem Renaissance Poets - Essay Example At this time, the sun was setting, and he still had a long journey to cover. In the first short stanza, the poem’s speaker mentions that he has ‘known rivers which are ancient as the world as well as older than the blood flow in human veins’ (Huggins, 2007). From this point of the poem, there are images of veins taking form of canals running throughout the human body and similar images of due rivers which wind around. They take the form of veins in shape where the levels of understanding within the poem in relation to the blood or water are based on the roots and circuits. Similar to veins or rivers, the roots run deep twisting irregularly into the medium which they are planted in. The ancient rivers mentioned by speaker are similar to the blood across veins and the roots through which trees are able to provide sustenance while still giving and supporting life. This is further supported as the speaker discusses the earliest forms of civilizations which thrived wit hin the river system and hence the theme developed by ‘roots’ bears dual meaning. The poem qualifies as one of Hughes’s most famous works which was celebrated as the soul and the voice within the black community in a time of intense racial inequality, injustice, and intolerance in America (Williams, 2010). Through the poem, Hughes managed to unite and inspire the black community in times when their voice was not appreciated by the white society predominantly.

Summary What Leaders Really Do) - Assignment Example An organization cannot run in the expected manner if those working under the leader do not receive direction to follow. This direction is very essential in bringing about the desired changes, which is why leaders ought to be on their toes so that these goals can be attained; to help an organization be able to cope as they struggle through it. Leaders do not have to produce a detailed plan on what is to be done, setting direction is the main aspect they are supposed to deal with and leave the rest to the management. There is nothing fascinating about leadership, but the fact that they develop visions that make way for changes, and work towards achieving them. For these changes to get realized, it is necessary that leaders with outstanding competence are selected and exposed so that they can come out with strong leadership. It is however useless having strong leaders with management that is weak, as performance will still be low. An example of visionary leadership that is set to bring about changes in an organization is that American Express at the time it was receiving a lot of competition from other companies that came up with cards to compete with them. Competition is known to hinder growth of a company and being the visionary leader he was, he decided to come up with a scheme that would put the company at its feet again; which was through asking of fundamental questions on economics, market and competition so that he could develop a perfect understanding of the business. It is the above that a leader should do as his dedication made him save the company. In aligning of people, communication is very important, and it is best that leaders be good at it. These challenges are in trying to get people understand a new or alternative vision to be implemented as well as having the people one is dealing with believe the message being put across. Alignment leads to empowerment, which ends up reducing on

Cross-Cultural Study of Sex and Gender Assignment

Cross-Cultural Study of Sex and Gender - Assignment Example It has been widely known that all of those given parameters contain provoking issues that affect the whole society throughout history. There is no excuse for all forms of societies around the world have one or more of those problems. Each problem has its own topics of debates among the societal members. The pros and the antis regarding specific issues take their stance by proving the other side as wrong. They present details to support their claims and arguments are sometimes placed in a book form where they show all of the details. They explain those arguments as much as they can and share those with other people. Though that may be the case, some books do not side with any argument as they try to objectively study, analyze and present the issues and the probable solutions from both sides. As mentioned above, those issues are very important to solve though they already exist for decades. One of those is the issue of sex and gender and how the society views it. As a topic, it is a broad and controversial concept with many issues deep within. The concept is not restricted to the view on the sex as an act pertaining intercourse but also includes genital health, pregnancy, gender orientation, gender equality, and many more.

leonardo da vinci Essay -- essays research papers

Leonardo da Vinci Da Vinci was born April 15, 1452, and died May 2, 1519. He would wear pink to make his complexion look fresher. Leonardo never attended public school. He was raised by his single father (http://www.yesnet.yk.ca/schools/projects/renaissance/davinci.html). In the mid-1460s the family settled in Florence, where Leonardo was given the best education that Florence, the intellectual and artistic center of Italy, could offer. In Verrocchio's Baptism of Christ (http://www.geocities.com/ksalce2001/biography.html). Leonardo had no interest in women; he spent most of his time painting. Five years later he became a member of the guild of St. Luke, a painters' guild in Florence. Four years later he worked as an independent artist at his own studio in Florence (http://www.yesnet.yk.ca/schools/projects/renaissance/davinci.html). In 1483 he started to paint the first version of theVirgin. He finished it in 1485. In 1495 he made a clay model for the statue of Francesco Forza, and put it on display. In 1486 he began to explore human flight. In 1500 he went to Mantua. Da Vinci studied philosophy, natural history, anatomy, biology, medicine, optics, acoustics, science, mathematics and hydraulics (http://www.yesnet.yk.ca/schools/projects/renaissance/davinci.html). Da Vinci was an architect, musician, engineer, scientist and inventor. He sketched the first parachute, first helicopter, first aeroplane, first tank, first repeating rifle, s...

Research Paper for Meyers Briggs Essay

According to the Myers Briggs Type Indicator, I am classified as an ESFJ—Extraverted, Sensing, Feeling, and Judging. I scored 56% on extravert—being outgoing, loud, non-secretive. I prefer to sense things rather than trusting my intuition by only 12%. I scored highest on the feeling over thinking category with 62% towards feeling. There was only an 11% difference between judging vs. perceiving. â€Å"Guardians of birthdays, holidays and celebrations, ESFJs are generous entertainers. They enjoy and joyfully observe traditions and are liberal in giving, especially where custom prescribes. All else being equal, ESFJs enjoy being in charge. They see problems clearly and delegate easily, work hard and play with zest. ESFJs, as do most SJs, bear strong allegiance to rights of seniority. They willingly provide service (which embodies life’s meaning) and expect the same from others.† (Joe Butt, Extraverted Sensing Feeling Judging). I first heard about the test abo ut a year ago when my sister had to take it for her work, so I had a decent guess of what my results would be, if I ever got the chance to take the test. I pegged myself pretty well. The only thing that really did surprise me though, were the numbers of how strong/weak I was in each field. After finishing the test, I reviewed the article about the most common careers for ESFJs. It states; â€Å"ESFJs often find themselves in occupations that either involve a lot of direct interaction with other people (e.g. clients, other staff members) or involve responsibility for critical tasks (e.g. require thorough attention or may have serious consequences), or both† (Career Choices For Your Life). Ever since I was little I have wanted to study zoology in college. The description of an ESFJ’s career is somewhat accurate to my dream career of being a zoologist. I will not have direct interaction with people as much as I will with animals. One of the responsibilities of a zoologist is to assess the dietary needs of the animals—planning what a tiger eats for dinner is a critical task that could very well have serious and even fatal consequences. The results of my test fueled my drive to master zoology throughout my college career. These types of tests are always very interesting to me, I love learning new things about myself, and how I process information. The combined knowledge of the results of every test—personality, learning style, etc.—will help me to become more successful in life. Also, knowing how I learn and process information helps me understand that other people mightlearn differently than I do. Being able to comprehend my learning and personality styles at such an early age will give me more time to learn ways to teach, understand, and work with others who have a different style than I do. One of the most interesting things I learned by taking this test, was finding out the famous people who were ESFJs too, I had no clue that Martin Luther King and Eleanor Roosevelt were ESFJs! Knowing that these inspirational people understood things the same way that I do enlightens me to know that I too can be as big of an inspiration as they were.
