Answer to Question #89771 in Molecular Physics | Thermodynamics for Shivam Nishad

Question

What is Joule-Thomson effect ? Obtain the
expression for Joule-Thomson coefficient for an Ideal gas.

Answer 1

The Joule-Thomson effect is the change in gas temperature during its stationary adiabatic flow through a porous partition. This effect is explained by the dependence of the internal energy of a real gas not only on temperature, but also on volume, and on the presence of real gas molecules of the potential energy of interaction. For an ideal gas, the Joule-Thomson effect is absent, i.e.

$$\mu_{G-T} = 0$$
