Let's say gas is not an ideal gas.(Freon 12)
We know the volumes of both sides. Also the mass and the initial pressure of gas.
I think we can't use W=PdV because pressure is not constant. Is there a way to do it?
Edit: By the way the temperature will change but in the end returns to its initial value. So heat transfer will occur through the boundaries.
