WebSee Answer. Question: A bomb calorimeter, or constant volume calorimeter, is a device often used to determine the heat of combustion of fuels and the energy content of foods. Since the "bomb" itself can absorb energy, a separate experiment is needed to determine the heat capacity of the calorimeter. This is known as colibroting the calorimeter. WebBomb calorimetry is used mainly in the scientific study of thermodynamic processes. It measures the heat of combustion produced in a chemical reaction. Also, it measures reaction enthalpy and change in enthalpy throughout the reaction. Obviously Bomb calorimeter is very essential to scientific and theoretical thermodynamic studies.
