A) 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 0.429-g sample of benzil (C14H10O2) in a bomb calorimeter containing 1100. g of water. The temperature increases from 24.80...
