Physics
The principle of calorimetry is based on :
- law of conservation of heat
- law of conservation of energy
- both (1) and (2)
- conservation of momentum
Answer
both (1) and (2)
Reason — Law of conservation of energy states that energy cannot be created or destroyed, only transferred or transformed from one form to another. In calorimetry, heat energy is exchanged between a system and its surroundings, but the total amount of heat energy in the system and surroundings remains constant, in accordance with these conservation laws.
