A chemical engineer claims to have devised a closed device, operating isothermally at 300 K, that could expand 100 mol of methane (assumed to be an ideal gas) from 1.0 to 0.4 MPa, and in the process generate 250 kJ of useful work. Should we believe this claim? Answer the question by calculating the change in entropy of the system, the change in entropy of the surroundings, and the total change in entropy of the universe.
