A bomb calorimeter, or constant volume calorimeter, is a device often used to determine the heat 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 0.322-g sample of phenanthrene (C14H10) in a bomb calorim containing 1050. g water. The temperature increases from 25.30 °C to 27.70 °C. The specific heat capacity of water is 4.184 J g-l °C-!. The combustion enthalpy is –7054 kJ/mol phenanthrene. C14H10(s) + 33/2 02(g) –14 CO2(g) + 5 H2O(1) A,H° = -7054 kJ/mol Calculate the heat capacity of the calorimeter. heat capacity of calorimeter = J/°C
