Problem 21.7: Find the entropy of an expansion

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., kB = 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.
