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 0.533-g sample of benzil (C1H100,) in a bomb calorimeter containing 1100. g of water. The temperature increases from 25.80 °C to 28.90 °C.
Water
The heat capacity of water is 4.184 Jgl°c-1
The molar heat of combustion is -6784 kJ per mole of benzil.
