A bomb calorimeter, or constant volume calorimeter, is a device often used to determine the heat of combustion of fuels and the energy available from 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 calibrating the calorimeter. In the laboratory a student burns a 0.770-g sample of isophthalic acid (C8H604) in a bomb calorimeter containing 1090. g water. The temperature increases from 24.30 °C to 27.00 °C.
