Calculate the entropy change for 1 mol of a diatomic gas when it expands from its initial volume of 5 L and 31.5°C to:
(a) a final volume of 25L reversibly and isothermically.
(b) irreversibly and isothermically against an external pressure of 1 atm.
(c) a final volume of 25 L reversibly and adiabatically.
Yes, it is zero, but you have to demonstrate it.
(d) irreversibly and adiabatically against an external pressure of 1 atm.
(e) For all cases above, calculate also the change in entropy for the surroundings and the
