Investigating The Total Heat Energy Released - 1963 Words

Data Analysis In order to determine the total heat energy released by each of the fuel sources, a graph will need to be constructed to demonstrate the change in the temperature of water over the entire duration of the experiment. From this graph, a linear trendline will be created for the last 3 data points where the water was allowed to cool, which can be extrapolated backwards to determine the total decrease in the temperature of the water due to a loss of energy to the surrounding environment during the combustion of the fuel. The difference between the highest and lowest temperature values will then be used to calculate the total change in the temperature of water during the combustion of the fuels. Below, one representative graph and†¦show more content†¦Density of water = mass of watervolume of water mass of water = (0.998 g cm-3)(80.0 mL  ± 0.5 1cm31 mL) , given that the density of water at 20.1  °C is 0.998 g cm-3 mass of water = (0.998 g cm-3)(80.0 cm3  ± 1%) mass of water = 79.8 g  ± 1% mass of water = 79.8 g  ± 0.8 q=mcT q=(79.8 g  ± 0.8) (4.18 Jg-1K-1)(71.8 K  ± 0.2), given that the change in temperature, in  °C, is equivalent to the change in temperature in K. q=(79.8 g  ± 1%) (4.18 Jg-1K-1)(71.8 K  ± 0%) q = 23900 J  ± 1% q = 23900 J  ± 200 q = 23900 J  ± 200 1kJ1000J q = 23.9 kJ  ± 0.2 Sample calculation 3: calculations performed to determine the total heat energy released per mole of the kerosene during its combustion for the first trial. Energy per mole = q(initial mass of spirit lamp with kerosene- final mass of spirit lamp with kerosene) MM of kerosene Energy per mole = 23.9 kJ  ± 0.2 (115.93 g  ± 0.01 - 114.45 g  ± 0.01) 170.38 g mol-1 , given that the main hydrocarbon in kerosene is C12H26 Energy per mole = 23.9 kJ  ± 1% 1.48g  ± 1% 170.38 g mol-1 Energy per mole = 2750 kJ  ± 2% Energy per mole = 2750 kJ  ± 50 The final values for the energy per mole for all trials can be averaged to reduce random experimental error. Once the calculations above are repeated for all fuel sources, the summarized results can be shown, in comparison to literature values for the heat of combustion to determine the most

Persuasive Essay Topics on Religion - Why Faith is Not an Enemy and How to Use It to Win With Consistent Writing

Persuasive Essay Topics on Religion - Why Faith is Not an Enemy and How to Use It to Win With Consistent WritingPersuasive essay topics on religion often offer a straightforward and unifying model for the delivery of persuasive writing in general. In this piece, I'll look at how you can harness this model for your own essay topics on religion.The most compelling reason for writing a persuasive essay on religion is that it simply works. Religion, more than any other subject, is a topic that very few people truly agree upon. Some people see religion as an enemy; others see it as a force for good.It's impossible to answer the question of what religion actually is - and even if you could, free-market capitalism would still provide a better alternative - with a straight answer. But by discussing the core foundations of religious faith, a persuasive essay can be a non-partisan way to present an issue that many other essays on religion will barely touch.Religious belief is a deeply personal matter that is made more complicated by a growing public distrust of religion. This mistrust is fed by tabloid reporting and partisan rhetoric and backed up by public relations campaigns that portray religion as a force for evil.But by focusing on the core beliefs of faith, persuasive essay topics on religion can present a different view. People from differing religious backgrounds can agree on the rightness of their positions, but still disagree on the best way to present their beliefs. This can result in a debate that brings out the best of both communities.'Religion and morality' essays on religion are one example of how this can work. If you can present a model for persuasion that helps explain why your core beliefs can be both virtuous and moral, then you have a better chance of convincing readers to change their views. By presenting the strong points of your faith, you can convince them to support your arguments.How can you bring this element into your own essay topics on rel igion? Simply, by understanding the reason behind the conflict between science and religion. This is a major dividing line in modern society, so you will need to demonstrate some reason behind why a scientific worldview can be justified as the best available answer to the questions of 'What is the meaning of life?' and 'What should people do about it?'By showing that there is a well-supported set of core beliefs that underpin morality and meaning, you are more likely to build a strong, cohesive and convincing argument for the conclusion that 'scientific facts must be reconciled with religious claims.' This is the basis for successful persuasive essay topics on religion and it will provide readers with the sense of security that they will find something good, even when they consider the topics that have most captured their attention.
