Please wait for the animation to completely load.

There is a time delay—since the system must be in equilibrium—before the change of state occurs.

In this animation N = nR (i.e., k_B = 1). This, then, gives the ideal gas law as PV = NT. Restart.

How much heat is added to or removed from the gas during the expansion of the ideal gas?
