I'm stuck on a question that involves the following concept:
If I have a system of two thermally isolated cylinders with pistons, A and B. And I do work on A, in such a way that it has constant pressure, does that mean that B also has constant pressure? Also does that mean, since $PV^\gamma$ is constant that the volume stays constant, throughout the process. Or, if there is some pressure difference would there be any way to calculate the relation between te initial volume and the final volume.
Also how would you calculate the work on this sytem, could you just see cylinder A as a seperate system and calculate the work on that, or is there some work done on cylinder B aswell?
Edit 2 The exact statement of the problem: Two thermally insulated cylinders, A and B, of equal volume, both equipped with pistons, are connected by a valve. Initially A has its pistion fully withdrawn and contains a perfect monatomic gas at temperature T, while B has its piston fully inserted, and the valve is closed. Calculate the final temperature of the gas after the following operation. The thermal capacity of the cylinders is to be ignored
Piston B is fully withdrawn and the valve is opened slightly; the gas is then driven as far as it will go into B by pushing home piston A at such a rate that the pressure in A remains constant: the cylinders are in thermal contact.
