The working substance of a heat engine is 1.00 mol of a monatomic ideal gas. The engine operates in a cycle in these steps: (1) the cycle begins at Pa = 1.00 atm and Va = 10.0 m³, (2) the gas is heated at constant volume to P = 3.00 atm, (3) It then expands at constant pressure until it is 40.0 m³. (4) 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. Show this cycle on a PV diagram (modified from Tipler, 2008)

Question
Based on cyclic process of energy flow diagram of a heat engine, answer the ff:
The working substance of a heat engine is 1.00 mol of a
monatomic ideal gas. The engine operates in a cycle in these
steps: (1) the cycle begins at Pa = 1.00 atm and
Va = 10.0 m³, (2) the gas is heated at constant volume to
Po
= 3.00 atm, (3) It then expands at constant pressure until
it is 40.0 m³. (4) 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. Show this cycle on a PV
diagram. (modified from Tipler, 2008)
