Use appropriate Maxwell relations to find an expression for how the entropy changes with volume at constant temperature for a van der Waals gas. Compare this to the corresponding expression for an ideal gas and speculate about the difference.

Which one of the following processes is endothermic? Water freezes to form ice. Propane gas burns in a gas grill. Water evaporates from your skin after stepping out of the shower. Steam condenses to liquid water. Liquid sodium freezing to a solid.

Using Boltzmann’s equation, calculate the entropy of a system consisting of one mole of gas in which each molecule of gas has 10 possible microstates. How does this value compare with the standard molar entropy of helium gas (see lecture slides for examples of standard values!). (Boltzmann’s constant k = 1.38 x 10-23 J/K)
