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
1.23gsample of
L-ascorbic acid
(C_(6)H_(8)O_(6))in a bomb calorimeter containing
1030gof water. The temperature increases from
25.80\deg Cto
29.00\deg C. The heat capacity of water is
4.184(J)/(g*\deg C). The molar heat of combustion is
-2340kJper mole of L-ascorbic acid.
