Synopsis

Intended for 'O' level students. The film begins with an explanation of the conceptualisation of energy quantities, and shows how the reaction of zinc and copper sulphate can release heat or electrical energy depending on how it is conducted. The problem of obtaining maximum work from a process is covered using a mechanical analogue of a potentiometer and this is related to the voltage obtained from a chemical change. Finally, the problem of energy losses due to the thermal wastage is discussed and the connection with maximum work and electrical energy explained.
