AI Thread Summary
Expanding a non-ideal gas reversibly and isothermally from volume V1 to V2 at constant temperature T is theoretically possible, similar to ideal gases. The first and second laws of thermodynamics apply universally, regardless of the gas's ideality. An infinite heat capacity reservoir is necessary to maintain constant temperature during the expansion. Additionally, the expansion must occur very slowly to ensure reversibility. Therefore, while challenging, it is feasible to expand non-ideal gases in this manner.

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.

You also need to expand it REEEEALLLY slowly...:biggrin:
 

Thread 'Off resonance driving of a MW/RF cavity'

Hello! Let's say I have a cavity resonant at 10 GHz with a Q factor of 1000. Given the Lorentzian shape of the cavity, I can also drive the cavity at, say 100 MHz. Of course the response will be very very weak, but non-zero given that the Loretzian shape never really reaches zero. I am trying to understand how are the magnetic and electric field distributions of the field at 100 MHz relative to the ones at 10 GHz? In particular, if inside the cavity I have some structure, such as 2 plates...
