Mechanical equivalent of heat
Principle: In this experiment, a metal test body is rotated and heated by the friction due to a tensed band of synthetic material. The mechanical equivalent of heat for problem 1 is determined from the defined mechanical work and from the thermal energy increase deduced from the increase of temperature. Assuming the equivalence of mechanical work and heat, the specific thermal capacity of aluminium and brass is determined.
Tasks:
1. Determination of the mechanical equivalent of heat.
2. Determination of the specific thermal capacity of aluminum and brass.
