Intermolecular forces play an important role in determining thethermodynamic properties of fluids. To see this, consider thevaporization (boiling) of water in frictionless piston-cylinderdevice shown below.

a) Compute the work obtained from the pistonwhen 1 kg of water is vaporized to steam at 100⁰C.
b) Calculate and show that the heat requiredfor the vaporization of the steam is considerably greater than thework done. So, what happens to the remaining of the heat suppliedto the system?
