Question

What is the principle of Calorimetry?

Answer 1

1. The branch of physics that deals with the measurement of heat energy is called ‘Calorimetry’.
2. The principle of calorimetry is based on the law of conservation of energy.
3. It states that the energy in a system can neither be created nor it can be destroyed and the sum total of energy is a constant quantity.
4. If no heat is transferred to the surroundings, then the heat lost by the hot body = the heat gained by the cold body.
