How does the Heat Energy given out during the Combustion of Alcohols Change as the Carbon Chain of the Alcohols used is increased? Aim My aim for this investigation is to find out how the heat energy released during the combustion of alcohols change as the carbon chain of the alcohols is increased. I will be using the following equation for the reaction to take place: Alcohol + Oxygen Carbon Dioxide + Water I will be substituting the alcohol with the following: * * Pentonal * Ethanol * Propanal * Butanol * Methanol I will also be using the formula below to work out what ?H is: ?H = Mass of Water x Specific Heat Capacity of Water x Temperature change Background Knowledge In Chemistry, there are two terms that mean giving out energy and taking energy in. These two terms are Exothermic and Endothermic. Exothermic is a reaction that gives out energy, normally in the form of heat. It is observed by an increase in temperature....
