Joule Thomson Effect

jarman007

It occurs when a real gas is allowed to expand adiabatically


we all know when a ideal gas is expanded adiabatically it temperature decreases
so real gas should do the same with minor difference




so what is all the fuss about we all know it will happen

why is it given a special name

Question: did you look at wikipedia before posting?

You seem to be thinking of isentropic, not general, adiabatic expansion.

This can increase temperature.

So unique thing about joule thomson effect is increasing of temperature on expansion

In addition to the above comments, historically, measurement of the Joule-Thompson coefficient led to the development of the absolute (Kelvin) temperature scale.
