Beginning with a pressure of 2.20 × 105 Pa and a volume of 6.34 × 10-3 m3, an ideal monatomic gas (γ = 5/3) undergoes an adiabatic expansion such that its final pressure is 8.15 × 104 Pa. An alternative process leading to the same final state begins with an isochoric cooling to the final pressure, followed by an isobaric expansion to the final volume. How much more work does the gas do in the adiabatic process than in the alternative process?
