96. Perfect diatomic gas (ν = 3 mol) occupies a volume V1 = 5 liters and pressurized p1 = 1 MPa, subjected isochoric heating to T2 = 500 C. Thereafter, the gas was subjected to an isothermal expansion of the initial pressure, and then it is the result isobaric compression returned to its original state. Plot cycle and determine the thermal efficiency of the cycle.
