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 0.796-g sample of glutaric acid(C5H8O4) in a bomb calorimeter containing 1000. g of water. The temperature increases from 25.70 °C to28.30 °C....
