Heat capacity of metals with Cobra4
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
- Flexible experimenting thanks to wireless data transmission
- Data acquisition with tablets possible
- Simplified implementation: all pre-settings already prepared
