Question 1: (a) An ideal gas is expanded reversibly and ad- iabatically. Decide which of q, w, AU, and AH are pos- itive, negative, or zero. (b) A 1.25 mole sample of an ideal gas is expanded from 320. K and an initial pressure of 3.10 bar to a final pressure of 1.00 bar, and CP, m = 5R/2. Calculate w for the following two cases: %3D Condition: The expansion is isothermal and reversible.
