Thermometer Ignition wires heat sample 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. 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 0.485-g sample of diphenyl phthalate (C20H1401) in a bomb calorimeter containing 1170. g of water. The temperature increases from 26.00 C to 28.50 C. The heat capacity of water is 4.184 Jgloc-1 The molar heat of combustion is -9382 kJ per mole of diphenyl phthalate. C20H140.5) + 43/2 O2(g) +20 CO2(g) + 7 H2O(1) + Energy Calculate the heat capacity of the calorimeter. heat capacity of calorimeter = JC Insulated outside chamber Sample dish Burning sample Steel bomb Combustion (bomb) calorimeter.
