1. Is the Joule-Thomson throttling process adiabatic? Is it isentropic? Explain each answer.
2. (a) Suppose that you have two sets of four distinguishable coins, and you flip all four coins in each system. How many different possible states are there?
(b) Now suppose that the two sets each contain four identical coins, and you flip all four coins in each set, keeping the two sets separate from each other. How many different possible states are there?
(c) Now you combine the two sets into one set of eight identical coins, all of which you flip. How many different possible states are there now?
