As long as the heat capacity is Cp=(7/2)R, one mole of gas is adiabatically compressed at 25 degrees in the piston and cylinder device to 7 bar from a state of 2 bar. This process is irreversible and requires 35% more work than the reversible insulation process from the initial state to the same final pressure state. What is the entropy change of this gas?
