Investigation on Energy released from Combustion of Alcohols Our experiment was designed to investigate which alcohol released the most energy when burned. Our plan was to measure the mass of the alcohol combusted when heating a specific volume of water to a specific temperature. We conducted this experiment on 5 different alcohols: Methanol, Ethanol, Propanol, Butanol and Pentanol. This was repeated 3 times for a better spread of results. These are our results. This table shows the mass of alcohol used to heat 20ml of water from 23o C (Room temp.) to 60o C. Pentanol lost the least mass when heating the water. When an alcohol burns it reacts with Oxygen to produce CO2 and Water. For Example, Methanol: Methanol + Oxygen Carbon Dioxide + Water CH3OH + O2 CO2 + H2O When this reaction occurs, chemical bonds are broken. Energy is needed for this to happen. New bonds are formed between the atoms in the products. When this happens, energy is released in...
