One kg mole of an ideal gas is compressed isothermally at 127 degrees C from 1 atm to 10 atm in a piston and cylinder arrangement. Calculate the entropy change of the gas, the entropy change of the surroundings and the entropy change of the "universe" resulting from the process if:

a) The process is mechanically reversible and the surroundings consist of a heat reservoir at 127 degrees C.

b) The process is mechanically reversible and the surroundings consist of a heat reservoir at 27 degrees C.

c) The process is mechanically irreversible, requiring 20% more work than the mechanically reversible compression and the sorroundings consist of a heat reservoir at 27 degrees C?
