Heat Capacity

The amount of heat required to raise the temperature of a body through 1K. Units of heat capacity are JK^-1

Constant volume:
Constant pressure:
Difference in heat capacities:
Ratio of heat capacities:
where: C_V = Heat capacity at constant volume; C_P = Heat capacity at constant pressure; Q = Heat; T = Temperature; V = Volume; U = Internal entropy; S = Entropy; P = Pressure; H = Enthalpy; β_P = Isobaric expansivity; γ = Ratio of heat capacities; κ_T = Isothermal compressibility; κ_S = Adiabatic compressibility

Heat capacity is an extensive property.
