Thermometer Stirrer 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. Ignition wires heat sample 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. Water In the laboratory a student burns a 0.788-9 sample of glutaric acid (C5H204) in a bomb calorimeter containing 1120. g of water. The temperature increases from 24.80 °C to 27.10 °C. The heat capacity of water is 4.1843 g 10c-1. The molar heat of combustion is -2151 kJ per mole of glutaric acid.
