Comparing fuels Plan In this investigation I will be burning alcohols to heat up a test tube of water. I will be burning five alcohols, methanol, ethanol, propanol, butanol and pentanol. The aim is to find out how much energy is produced when burning these alcohols. Alcohols react with oxygen in the air to form water and carbon dioxide. When hydrocarbons are burnt they are oxidized, meaning carbon dioxide and water is made. The reaction that is involved in burning alcohols is exothermic because heat is given out. Form this reason the reactant energy is higher than that of the product. The energy is given out when forming the bonds between the new water and carbon dioxide molecules. The amount of energy made by exothermic reactions like this can be worked out by using the formula Heat J = temp rise ?C X Mass water g X 4.2 J/g?C. The...
