a) One mole of an ideal gas, Cy = R, is expanded adiabatically and reversibly: Initial state: 300 K, 1 atm; final state: 0.5 atm. Calculate q, w, AE and AS. b) The same gas, initially at 300K and 1 atm is expanded adiabatically against a constant opposing pressure equal to the final pressure, 0.5 atm. Calculate q, w, AE and AS.

A 220-ft3 sample of gas at standard temperature and pressure is compressed into a cylinder, where it exerts pressure of 2000 psi. Calculate the work (in J) performed when this gas expands isothermally against an opposing pressure of 1.0 atm.
