Burning alcohols INTRODUCTION - In this investigation I am going to burn five different alcohols in order to heat up a beaker of 100ml3 water. The alcohols that I will be burning are methanol, ethanol, propanol, butanol and pentanol. The burning of alcohols involves an exothermic reaction because heat is given out. Therefore the reactant energy is greater than that of the product. PLANNING - Aim: The aim of this investigation is to investigate the amount of heat produced by burning five different alcohols (which are listed above). Variables: The independent variable (things you change) will be the five different alcohols which I will investigate to see the amount of heat produced. I will measure their mass in g using an electrical weigher. The dependant variables (things you measure) are the increase in temperature, the mass before and after the experiment of the five variables, changing the water after every experiment and adjusting the clamp...
