2. Take the entropy to be a function of the independent variables T and V. For the van der Waals gas, derive an expression for the entropy as a function of volume at a given (fixed) temperature. Hint: You will want to take advantage of Maxwell's relations. Your answer will contain an undetermined constant of integration.

Entropy of a dice: What is the average dice roll and entropy of an unbiased dice (6 sides)? If the probabilities are p1 = ⅛ p2 = ¼ p3 = ⅛ p4 = ⅛ p5 = ¼ p6 = ⅛ (p1 is the probability of rolling a 1 p2= probability of rolling a 2 etc.). What is the average dice roll and entropy? Explain why the dice is or is not biased.
