Abstract: The objective of this experiment is to investigate the energy content of the hydrocarbons Ethanol and Propanol, by using them to heat water in a soda can. In this experiment two trials will be performed per hydrocarbon. Each hydrocarbon will be used to raise a certain amount of water 20 C and then the amount of fuel used to do so will be measured. In the experiment, ethanol burned a greater amount of fuel than propanol did, and therefore provided less energy per mass unit. From this experiment it can be determined that because the ethanol trials consumed more fuel to achieve the desired difference in temperature ethanol therefore provides less energy than propanol. Introduction: The energy problems we are experiencing in the US stem from our country’s dependence on fossil fuels. To relieve our dependence on oil as fuel, alternative fuels are being explored. There are several advantages of avoiding the use of fossil fuels, such as increased domestic energy production and cleaner burning fuel which leads to less air pollution. Decreasing the amount of pollution given off is an important issue in today’s society because we are facing the results of years of pollution given off by burning oil, which has resulted in extreme global climate change. Alternative fuels, such as alcohol based fuels and bio-fuels, are becoming more attractive because of these fuels are renewable, and would also support domestic agriculture. The experiment investigates the energy released by two alcohol based fuels by using the burning fuel to heat water. The fuels will be compared to determine which fuel produces the most energy for the mass of the fuel burned. The experiment will also address the effects related to oxygenation of fuel on the fuel’s energy output. Materials and Methods: The study is designed to investigate the energy content of two hydrocarbons by using them to heat water; this is accomplished by weighing a fuel burner and then using it to heat a certain amount of water 20 ° C. Then the fuel burner is weighed again and the difference in weight is recorded. Obtain a dry soda can and remove the top. Cut two holes in it so that a glass rod can be
