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 0.524-g sample of 2-naphthylacetic acid (C₁pH1002) in a bomb calorimeter containing 1070. g of water. The temperature increases from 24.50 °C to 27.60 °C. The heat capacity of water is 4.184 Jg-¹°C-¹. The molar heat of combustion is -5779 kJ per mole of 2-naphthylacetic acid.
