... SKILL AREA P: PLANNING Aim To investigate how the amount of heat produced by burning a fuel depends on the mass of fuel burned. Hypothesis I predict that the amount of heat energy produced by burning the fuel (we are using ethanol) will be proportional to the mass of ethanol burned. I have based this prediction on the following scientific knowledge (as suggested in a secondary source - 'Chemistry: A Practical Approach' by A.L Barker and K.A Knapp): Within the reactant molecules of a chemical reaction, there are many tiny atoms which are held together by very strong forces. These forces which link atoms in molecules together are called bonds. All chemical reactions consist of bonds in the reactant molecules being broken, and new bonds being formed. The chemical reaction that I am investigating is that of ethanol burning in oxygen to produce carbon dioxide and water, and this idea of
