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
