A bomb calorimeter, or constant volume calorimeter, is a
device often used to determine the heat of combustion of
Ignition

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.
