The diagram shows a simple calorimeter system for measuring the heat given out by a liquid fuel burner. The experiment data for four fuels A,B, C and D is given below. 100 ml (100g) of water was used in the calorimeter to 'collect' the heat given out. The mass of fuel burned and the temperature rise of the water are given.
