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.
Benefits
- Compact, easily transportable setup
- For both demonstration and student experiments
