A piston containing 0.75 moles of a perfect gas at 25 degrees C
is moved isothermally from a starting volume of 8.305 L.
Calculate the work in joules if the piston is moved irreversibly
against a constant external pressure of 4.100 atm. We weren't
giving final volume so I am unsure of what to do. I tried to use
P1V1 = P2V2 because the final pressure is equal to external
pressure in an irreversible process. But then my final volume...
