Unformatted text preview: follow the general functionality f(T) = T x/2 . (That is B(T) = T 1/2 , C(T) = T and D(T) = T 2 ) Now vary V m . At what value of V m does Z vary by only 1% over this temperature range? What happens to the plots? (You will need excel for this problem. We will discuss this briefly at the beginning of class on Friday. The computer lab across from my office has excel on the computers.) 3. Show the relationship between w rev and n, R and T for a. an ideal gas b. a van der Waals gas c. assuming the gas is H 2 , what is w rev for 1 mol expanded from 1 L to 2 L at 25 o C for both cases?
