Problem 2.150

An ideal gas was expanded from the initial state to the volume \(V\) without any heat exchange with the surrounding bodies. Will the final gas pressure be the same in the case of (a) a fast and in the case of (b) a very slow expansion process?

Reveal Answer
 The pressure will be higher after the fast expansion. \text { The pressure will be higher after the fast expansion. }
