Variable heat capacities

REVTEMP - Reversible Reaction with Variable Heat Capacities... 

The specific heat is the amount of heat required to change one mole of a substance by one degree in temperature. Therefore, unlike the extensive variable heat capacity, which depends on the quantity of material, specific heat is an intensive variable and has units of energy per number of moles (n) per degree.

Compression Work with Variable Heat Capacity... 

An analysis and computation of the non-homogeneous distribution of the temperature were first carried out by Mache [9], after whom we shall call this phenomenon the Mache effect. Lewis and Elbe [10] computed the effect taking into consideration the variable heat capacity and dissociation. 

By taking into account the variable heat capacity, we have...

The British thermal unit (Btu) the energy required to heat one pound of water through a temperature range of 1° (F). Because of the variable heat capacity of water, it was necessary with this unit, just as with the gram-calorie, either to specify the temperature of the water or to use a mean value. The 60-degree Btu and the mean Btu between 32 and 212° (F) were in common use. In both instances, a constant pressure of 1 atmosphere was included in the definition. 

Having considered the exothermic liquid-phase reaction with constant heat capacities, we new consider an endothermic g -phase reaction with variable heat capacities.
