Heat of combustion: Standards & Products

The heating value (or energy value, calorific value, heat of combustion) of a substance, usually a fuel or food (see food energy), is the amount of heat released during the combustion of a specified amount of it. The enthalpy of combustion is the same value expressed as an enthalpy, where release of heat is described as negative number.
