n = 6 moles of a monatomic ideal gas initially fills a V0 = 0.35 m3 container at P0 = 85 kPa. The gas undergoes an isobaric expansion to V1 = 1.3 m3. Next it undergoes an isovolumetric cooling to its initial temperature T0. Finally it undergoes an isothermal compressions to its initial pressure and volume.
