The equipment allows the amount of work done by thermal energy to be measured. Heat Engine Cycle: When the air chamber is moved from the cold water bath to the hot bath, the piston rises, lifting the 200 g mass to demonstrate work. and that can do useful mechanical work by lifting small masses from one height
