GCSE Science Coursework Title: Burning Fuels. What are you trying to find out? I will be carrying out an investigation, which allows me to calculate and compare how much energy/fuel is used to raise 100cmcubed of water to 20 degrees centigrade. I will be using 5 different fuels; Butanol, Pentanol, Propanol, Methanol and Ethanol. The aim is to find out how much energy is produced when burning these alcohols. Alcohol's react with oxygen in the air to form water and carbon dioxide. This is an exothermic reaction, meaning that when energy is put in, more energy is given off. The formulae of the alcohols that I will be using are. Methanol CH OH Ethanol C H OH Propanol C H OH Butanol C H OH Pentanol C H OH Prediction: I predict that the more bonds there are holding the carbon, oxygen and hydrogen atoms together; more energy will be required to break them...
