What is meant by calorimetry? State its principle.

Calorimetry is the measurement of heat lost or gained by an object.

The principle of calorimetry state that 'When a hot body is mixed with a cold body, the heat lost by the hot body is equal to the heat gained by the cold body, provided that no heat escapes to the surroundings.'

Therefore,  Heat lost = Heat gained.
