Bomb calorimetry is a technique used to determine the enthalpy of combustion, usually in O2, of a chemical species. A known amount of compound is placed inside a fixed volume container that is, in turn, filled with oxygen at a high enough pressure to ensure complete combustion. The fixed-volume container (the 'bomb') is then inserted into a bucket containing a precisely known volume of water. The oxygen and compound are ignited, and the temperature change in the water is recorded....

A constant-volume calorimeter was calibrated by carrying out a reaction known to release 1.15 kJ of heat in 0.700 L of solution in the calorimeter (q = -1.15 kJ), resulting in a temperature rise of 3.00 °C. In a subsequent experiment, 350.0 mL of 0.20 M HCIO, (aq) and 350.0 mL of 0.20 M NaOH(aq) were mixed in the same calorimeter and the temperature rose by 6.36 "C.
