The Joule-Thomson effect is also known as the Joule-Kelvin effect.

Joule-Thomson coefficient

The Joule-Thomson coefficient is given by

where T is the temperature, p is the pressure and H is the enthalpy.

In terms of heat capacities one has

and


In terms of the second virial coefficient one has
