2.3 Thermodynamics 2.3.3 Calorimetry
Heat capacity of metals
Principle Heated specimens are placed in a calorimeter filled with water at low temperature. The heat capacity of the specimen is determined from the rise in the temperature of the water. Tasks 1. 2. 3.
To determine the heat capacity of the calorimeter by filling it with hot water and determining the rise in temperature. To determine the specific heat capacity of aluminium, iron and brass. To verify Dulong Petit's law with the results of these experiments.
