Can i expand non-ideal gas reversibly isomermally?

[kntsy]

Suppose we expand the ideal gas reversibly isomermally from V1 to V2 at T, can i expand non-ideal gas reversibly isomermally from V1 to V2 at T

The first and second laws of thermodynamics do not depend on the matter involved.

In theory, you could expand a non-ideal gas or any substance isothermally and reversibly. All you need to do is have an infinite heat capacity reservoir.

All you need to do is have an infinite heat capacity reservoir.

You also need to expand it REEEEALLLY slowly...
