Determination of the enthalpy of combustion by a calorimetric bomb

C-AV-21/EV

The calorimetric bomb is used to fully burn substances under conditions of excess oxygen. The combustion heat released is absorbed by the calorimeter in which the bomb is immersed leading to an increase of ΔT temperature. The thermal capacity of the system is first determined by making a considerable amount of heat from the combustion of benzoic acid. Consequently, under the same operating conditions, the enthalpy of combustion of naphthalene is determined.
