the Calorific Value of Fuels Aim: To quantify the amount of energy produced by different fuels and to determine which fuel is more efficient (has a higher calorific value). Introduction: The easiest way to achieve our aim is by heating a substance with a known specific heat capacity and using the energy released from burning our fuels. This will give us the value of the heat energy released by the combustion of our two fuels. The chemical reaction for combustion: FUEL + O2

others. (Thus creating the phrase energy cannot be created or destroyed.) There are many advantages of using fossil fuel. One is that fossil fuel help reduce the time it takes time to getting one place to another. For example: Before fossil fuel it would take the average person days to go from one state to another or hours to get travel between cities. Also‚ in using fossil fuel Power plants could produce enough energy to power their homes‚ which includes lighting‚ heat‚ central air‚ and cooking

Intercontinental University Online Abstract In this paper I will talk about the pros and cons of different energy sources such as fossil fuels and nuclear energy. I will also discuss two provisions of my choice from the Energy Policy Act‚ 2005. The Pros & Cons of Different Energy Sources What are the pros and cons of fossil fuels? Fossil fuels are a source of non-renewable energy that we have been using a couple centuries now. They are an important source of energy that we have come

are the resources that cannot be reproduced/grown/generated or used scale which can sustain its consumption. Eg: Coal because it gets exhausted and long time to reform. When we use them and some other examples are LPG/nuclear/natural gas and fossil fuel are natural gas and nuclear energy. Although there has been many issues‚ people still use Non-Renewable Resources because capturing renewable energy still depends on use of non-renewable resources. For instance Sun is good example of renewable energy

It was estimated by the Energy Information Administration that in 2007 primary sources of energy consisted of petroleum 36.0%‚ coal 27.4%‚ and natural gas 23.0%‚ amounting to an 86.4% share for fossil fuels in primary energy consumption in the world.

which mainly comes from the burning of fossil fuels as a fuel source or for electricity. Alternative energy‚ also known as renewable energy‚ is a solution to the problems caused by fossil fuel burning. Many countries around the world are beginning to switch to renewable energy. Following this example‚ switching to alternative energy in America is a realistic solution to the problems caused by obtaining energy from nonrenewable sources. Fossil Fuels are natural materials

Cause of acid rain (10) The history of acid rain caused by human activities began with the industrial Revolution in about 1750. This is when steam power began to be used to drive machinery. This was when large amounts of fossil fuels (coal‚ petroleum and natural gas) began to be burnt in order to produce energy. The problem of acid rain became gradually worse until 20th century‚ scientists began to observe widespread environmental damage. Since the problem of acid rain is discovered
