Principle working and of construction of boys calorimeter?

Answer 1

A boy's calorimeter is designed to measure the heat transfer during physical or chemical processes, typically involving water. It operates on the principle of calorimetry, which states that the heat lost by a hot substance equals the heat gained by a cold substance. The construction usually involves an insulated container filled with water, a thermometer for measuring temperature changes, and a stirrer to ensure uniform temperature distribution. The heat exchange is calculated using the specific heat capacity of water and the measured temperature change.
