Investigate whether firelighter, wood, ethanol, paraffin or wax contains the most energy :: GCSE Chemistry Coursework Investigation

Investigate whether firelighter, wood, ethanol, paraffin or wax contains the most energy Energy In Different Fuels Aim: I am going to investigate which fuels contain the most energy between; firelighter, wood, ethanol, paraffin and wax. Prediction: I think that the fuel that contains the most energy is the one that produces the highest rise in temperature of the water. I know this because†¦ Heat + fuel + oxygen => CO2 + H20 + energy. The energy realised is heat and light energy, which is dependent on the chemical potential energy in the fuel. The greater the chemical potential energy the more energy is transferred as heat and light; the greater the rise in temperature. And because of the fire triangle: tri2.gif (22406 bytes) Apparatus: List: Stop watch Thermometer Splint Clamp Matches Boiling tube Heat proof mat Fuels: Firelighter, Wood, Ethanol, Paraffin, Wax. Method (Preliminary test): first of all, I will make sure I take all of the safety precautions, I.e. tie back long hair, use goggles and make sure the room is well ventilated. Secondly I will set out the apparatus and get all the equipment from the list (shown on the previous page). Using the measuring cylinder, I will put 20cm3 of distilled water into a boiling tube, and take the starting temperature. In order to make this a fair test I will burn the fuel for one minute only, use 20cm3 of water and make sure the tip of the fuel’s flame is under the boiling tube. After the minute is up, I will blow out the flame or place the lid of the fuel over it, (cutting off the oxygen). I will then take the finial temperature. Then I will repeat the experiment for the other four fuels, in order to establish which two fuels produced the highest rise in temperature of the water. Method - Comparison: I will then compare these two fuels by heating them until they get to a certain temperature noting down the time every time the temperature increases by 10 °C in order to form a scatter graph using line of best fit. I will use step one and most of step two from the preliminary test (first of all, I will make sure I take all of the safety precautions, I.e. tie back long hair, use goggles and make sure the room is well ventilated. Secondly I will set out the apparatus and get all the equipment from the list (shown on the previous page). Using the measuring cylinder, I will put 20cm3 of distilled water into a boiling tube,) I then heat the water using the first fuel until it rises to 100 °C, noting the time every 10 °C starting from 20 °C.

MBA admission

My long-term career goal is to manage a high-tech company in the field of electronics and communications. With over six years of experience in the technical aspects of high-tech product development, I bring considerable technical knowledge to this task, and hope to compliment this knowledge with a firm understanding of business fundamentals provided by the McCombs School of Business.My personal ackground is no less of an asset, as it allows me to understand people and business issues from a unique and mature perspective. I grew up in India and obtained a Bachelors and a Masters degree in Electrical Science from Delhi University. After that I attended the Indian Institute of Technology Kanpur and earned a second Masters degree in the field of laser technology. My professional career began in 1995 when I was hired by HCL-Hewlett Packard to work on computer hardware design in an office outside of Delhi.It was my first direct experience with state-of-the-art technology and the exciting e xperience convinced e to pursue a career in the high-tech arena. Within nine months, I traveled to the Netherlands to work as a consultant for Tulip Computers NV, then the largest manufacturer of computers in Europe. After six months abroad, I returned to India but was soon transferred by my parent company to NCR Corporation in South Carolina.Before I could be recalled, I left HCL-Hewlett Packard and looked for another Job since I had decided to settle in the United States. I worked briefly for an ill-fated start-up, but left when the company moved its operations to China. I started my current position at American Megatrends, Inc. , (AM') in 1998 and have been employed here for over three years. IVe been working on high-tech motherboard design and have worked my way up to the position of team leader.AMI has offered me a unique opportunity I haven't had in other positions: the opportunity to participate in all the steps of product development. As a pure engineering company, AMI has v irtually no high level management and the engineer is responsible for everything from product conception, to development, to manufacturing and marketing! I have seized upon this opportunity and greatly expanded my understanding of product development beyond the design stage. I interact very closely with the manufacturing group and have come to understand production issues.Understanding how our products are mass produced at the plant, and especially how the factory workers utilize the machines for manufacturing, has given me a perspective on human and material capital which will be of great use in management. I have also worked closely with the sales and marketing division, and have occasionally even traveled to customer sites. While I have gained much practical experience (both in terms of technology and in terms of leadership) through my work, I cannot see myself in the same position fifteen years from now.I want to take my electronics firm into a new direction and believe at tn th is vision can best be accomplished trom a position ot management. I have realized from my six years of work experience that a strictly engineering background is not sufficient to enable me to reach my goals. A sound understanding of business fundamentals, that can be obtained through the McCombs School of Business, will help me develop the management skills I need to analyze business situations and manage resources rationally.An MBA will build upon my practical experience and allow me to achieve a position of leadership. My personal struggle to obtain the life I have now has imbued me with an ambition to grow as an individual and to give back to the society that has given me so much. My practical work experience and unique outlook on life contribute toa compassionate leadership style and an ability to understand the needs of people from all levels of society.

He wants them to to become the best they can be. But that power for greediness has taken over him and changed him into a different person A person his own mother didn’t recognize. We can all learn from Walter Younger that money can corrupt oneself in without one knowing.

Gender-Friendly Military essays

Gender-Friendly Military essays Pride, morale and efficiency of the United States' Armed Services may be being toyed with by a rave of "gender equality". Military readiness and defensive ability of the United States are being jeopardized by the debate to be a kinder, more equal military. Since the Second World War the United States has been known for its supremacy in military capability, however there is a new challenge for these Armed services. Many new opinions see the military as a shining example of how a glass ceiling can deny women of their chance to compete equally with men. Traditionally shadowed with hard corps discipline, courage and challenging curricula, the United States has kept a combat ready force since we have become the superpower. However a new breed of soldier is to be implemented, one of the couch potato age. Why the couch potato standard? Because the former grueling and challenging training standards have been modified as of late to accommodate people of all physical abilities and people of bo th genders. Radicals have made their points clear that they believe that women belong everywhere men are in the Armed Forces. Females are gradually becoming more and more influential in today's military, meeting the new standards, and leading ground to a more gender friendly, but less combat friendly warfare. Conservatives state that the Armed Forces of the United States are being treated to much as a job force and not enough like a defense force. Women are expecting to be treated fairly and have equal opportunities in a job that they are generally not prepared for; This "gender equality" is leading to a weaker, kinder, and less productive military. But the equality that is valued so preciously in America is at stake. There must be a decision made, between the gender friendly service, and perhaps the harsh reality that does not include women on the front lines and in the trenches. Since the evolution to the All-Volunteer Force in nineteen seventy-three,...

Pope Clement VII Profile

Pope Clement VII Profile Pope Clement VII was also known as: Giulio de Medici Pope Clement VII is noted for: Failing to recognize and deal with the significant changes of the Reformation. Indecisive and in over his head, Clements inability to stand strong against the powers of France and the Holy Roman Empire made an unstable situation worse. He was the pope whose refusal to give Englands king Henry VIII a divorce touched off the English Reformation. Occupation and Role in Society: Pope Places of Residence and Influence: Italy Important Dates: Born: May 26, 1478, Florence Elected pope: Nov. 18, 1523 Imprisoned by the Emperors troops: May, 1527 Died: Sept. 25, 1534 About Clement VII: Giulio de Medici was the illegitimate son of Giuliano de Medici, and he was raised by Giulianos brother, Lorenzo the Magnificent. In 1513 his cousin, Pope Leo X, made him archbishop of Florence and cardinal. Giuliano influenced Leos policies, and also planned some impressive works of art to honor his family. As pope, Clement wasnt up to the challenge of the Reformation. He failed to understand the significance of the Lutheran movement and allowed his involvement in Europes political sphere to reduce his effectiveness in spiritual matters. Emperor Charles V had supported Clements candidacy for pope, and he saw the Empire and the Papacy as a partnership. However, Clement allied himself with Charles longtime enemy, Francis I of France, in the League of Cognac. This rift eventually resulted in imperial armies sacking Rome and imprisoning Clement in the castle of SantAngelo. Even after his confinement ended several months later, Clement remained under imperial influence. His compromised position interfered with his ability to deal with Henry VIIIs request for an annulment, and he was never able to make any viable decisions regarding the upheaval that the Reformation had become. edited by Kenneth Gouwens and Sheryl E.

Philosophy on Dualism Essay Example | Topics and Well Written Essays - 1000 words

Philosophy on Dualism - Essay Example Dualism graces its roots to as far back as Zarathushtra, although Plato and Aristotle also dealt with the possibility of existence of an incorporale souls that actually bore the faculties of intelligence and wisdom. Their conclusion is that "people's intelligence (a faculty of the mind or soul) could not be identified with, or explained in terms of, their physical body" (Wikimedia Foundation, Inc.). The difference in the properties of mental and physical realms supports the validity of dualism. Minds are observed to have subjective qualities such as sensations which cannot be reduced to something physical. These experiences then are deemed to be from of different origin than the physical body. "There is no place in the brain where electric stimulation can cause a person to believe or decide. Although our thoughts can be true or false our brain states cannot be true or false. Nobody can tell what we are thinking by measuring brain waves. We must be asked what we are thinking" (AllAboutPhilosophy.org). On the other hand, there seems to be a lack of rational understanding as to how an interaction could possibly take place between the brain and the mind. Simply, this arguments says that there is nothing such as supernatural or other dimension that can explain this interaction thus the mental and physical realm must be one. Another argument against dualism is that when the brain is damaged, brought by physical trauma, drug abuse and other diseases the mental powers are always affected. "The argument holds that if the brain and the mind were actually separate, our mental powers would not be comprised" (AllAboutPhilosophy.org). This views leads us to think that there is/are factor/s that dictate the well-being of the mind, not just the physical body. Mental heath then is a factor of many other things aside from physical health. In the end it is found that the arguments for dualism is strong. Indeed, things such as emotions or feelings which does not necessarily emanate from the physical body are from different realms and they affect the mind. Monism Monism is associated with any philosophical view which says that "there is unity in a given field of inquiry, where there is not to be expected" (Wikimedia Foundation, Inc.). Thus there are philosophers who stands on the belief that the universe is really just one thing, despite of its many facets, appearances, diversities. In theology, this is the belief in one God who holds everything. Just differ in what they target and how they count. There are actually many monisms, although they all have the attribute of oneness. We however focus on two historically important monism; the existence monism which targets concrete objects and counts by token and the priority monism which targets concrete objects and counts by basic token. However, "neither existence nor priority monism is accorded much respect in contemporary metaphysics, nor are they always properly distinguished. Indeed, the entire monistic tradition is often dismissed as being somewhere between obscure and ridiculous" (Stanford Encyclopedia of Philosphy). Monism can be viewed as simply the opposite of dualism and pluralism. It particularly denies multiplicity of things and the distinction between body and soul, matter and spirit and other dualistic distinctions. Strengths
