Problem 21.7

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.  Assume an ideal monatomic gas.  Restart. 

1. Identify the thermodynamic process. 
2. Draw a TS diagram and calculate the change in entropy.
