    Hey guy's I've been given some questions but I'm struggling to do these two, I'm trying to apply Pv=nRT but I'm guessing this is the wrong equation.

    1 mole of an ideal gas undergoes a reversible isoth ermal compression at 20°C from a pressure of 1 atm to 5 atm. Give values for the system of q, w, ∆ U, ∆ H and ∆ S.

    And this question.

    1 mole of an ideal gas of volume 1m3 expands adiabatically and reversibly against an external pressure of 2 atm to reach a volume of 1.5m 3. Give values for the system of q, w, ∆ U, ∆ H and ∆S.

    Thanks for any help!!

    the first few bits of this thermodynamics crib-sheet might help, if not now, at least some time in the near future.
