Calorimetry is the branch of Physics that deals with the measurement of heat exchanged during physical and chemical processes. It helps in determining the amount of heat gained or lost by a substance when its temperature changes.
Calorimetry is an important topic in Thermal Physics and is frequently included in JEE Main Physics.
Calorimetry is based on the principle of conservation of energy, where the heat lost by one body is equal to the heat gained by another body in an isolated system. The measurements are usually carried out using a device called a calorimeter.
Calorimetry is a frequently asked topic in JEE Main Physics. Questions are commonly based on heat exchange, thermal equilibrium, specific heat capacity, and practical applications. A strong understanding of calorimetry helps students solve both conceptual and numerical problems.
