Lauren Crawley 10 LE 6-March-2002 Enthalpy Experiment I will be trying to obtain reliable results which tell me the relationship between the number of carbon atoms, in particular alcohols: Methanol, Ethanol, Propan-1-ol and Butan-1-ol, and the amount of heat energy given out, known as the enthalpy of combustion. The combustion process is the making and breaking of bonds. In my experiment heat will be given out (it will be an exothermic reaction) In an exothermic reaction the products are at a lower energy level than the reactants, the difference is the heat energy. The complete combustion of an alcohol is when it reacts with oxygen in the air to form water and CO2. Fuel is a substance that is generally burned to produce thermal energy. Using these 4 alcohol fuels I aim to find out how much heat energy each alcohol produces. I am going to investigate this energy release by burning alcohol-...
