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 calibrating the calorimeter. In the laboratory a student burns a 0.284-g sample of phenanthrene (C14H10) in a bomb calorimeter containing 1020. g of water. The temperature increases from 24.60 °C to 26.80 °C. The heat capacity of water is 4.184 J g-¹°C-¹. The molar heat of combustion is -7054 kJ per mole of phenanthrene.
