A flask contains 90.7 moles of a monatomic ideal gas at pressure 5.64 atm and volume 40.1 liters (point A on the graph. Now, the gas undergoes a cycle of three steps: - First there is an isothermal expansion to pressure 3.79 atm (point B on the graph). - Next, there is an isochoric process in which the pressure is raised to P1 (point C on the graph). - Finally, there is an isobaric compression back to the original state...

The working substance of an engine is 1.00 mol of a monatomic ideal gas. The cycle begins at P1=1.00 atm and V1=24.6L. The gas is heated at constant volume to P2=2.00atm. It then expands at constant pressure until its volume is 49.2L. The gas is then cooled at constant volume until its pressure is again 1.00 atm. It is then compressed at constant pressure to its original state. All the steps are quasi-static and reversible. Calculate the TOTAL work done...
