Investigate the amounts of heat energy produced by the combustion of different alcohols in this class experiment. Includes kit list and safety instructions.

In this practical, students use a spirit burner to burn various alcohols while measuring and comparing the amount of heat energy produced. The investigation may be used as an introduction to fuels or, for older students, as preparation for a discussion about heat losses and incomplete combustion.
