Investigating Energy When Fuels Burn.

Investigating Energy When Fuels Burn Plan and aim My aim is to find out how much energy is released when different alcohols are burnt. There are many different variables including: * The type of alcohol. * Mass of alcohol in moles. * Mass of water in volume. * The height and shape of the can. * The starting temperature in (C. * The temperature rise of water. My input variable will be different types of alcohol. My output variable is the temperature rise of the water because I need this to be able to calculate the amount of energy released. I will use the following formula to calculate the amount of energy released by each alcohol: ENERGY = Mass of water x 4.2 (specific heat capacity) x temperature rise I will control the mass of fuel, mass of water, height and shape of the can and the starting temperature. I am going to control the other possible variables to make it a fair experiment. If I repeat each alcohol six times, this will allow me to calculate an average. This should help me to notice any odd results. If there are any anomalous results, they will not be included because they will make the average odd. I will need to wear goggles and tie back long hair for safety issues. The Bunsen burner will always be kept on a safety flame so it is visible. Prediction I predict that as the number of the carbons in the alcohol increases, the temperature rise in the
