Joule Thomson Effect: Exploring the Minor Difference

[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?

we all know when a ideal gas is expanded adiabatically it temperature decreases

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

so real gas should do the same with minor difference
so what is all the fuss about we all know it will happen

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.

- Joule Thomson Effect?

The Joule Thomson Effect is given a special name because it is a specific phenomenon that occurs when a real gas is allowed to expand adiabatically. While it is true that the temperature of an ideal gas will decrease when expanded adiabatically, the Joule Thomson Effect shows that real gases may not follow this behavior exactly. This is due to the intermolecular forces present in real gases, which can cause them to deviate from ideal gas behavior. The minor difference observed in the temperature change during adiabatic expansion of real gases is a result of these intermolecular forces and is known as the Joule Thomson Effect. It is an important concept in thermodynamics and has practical applications in various fields such as refrigeration and natural gas processing. Therefore, it is worth exploring and understanding this phenomenon in order to fully comprehend the behavior of real gases.
