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 0.304-g sample of biphenyl (C12H10) in a bomb calorimeter containing 1030. g of water. The temperature increases from 24.70 °C to 27.10 °C. The heat capacity of water is 4.184 J g-1°C-1, The molar heat of combustion is -6251 kJ per mole of biphenyl. C12H10(s) + 29/2 O₂(g) →12 CO₂(g) + 5 H₂0 (1) + Energy Calculate the heat capacity of the calorimeter. heat capacity of calorimeter = 3/°C Ignition wires heat sample Insulated outside chamber Water Stirrer Thermometer Sample Burning Steel sample bomb dish Combustion (bomb) calorimeter.
