Perfect diatomic gas in an amount of 3.0 mol occupies a volume V1 = 5 liters under pressure p1 = 1,0 MPa. Gas isochoric first heated to T2 = 500 K, and then isothermally expanded to the initial pressure. Then, isobaric compressed gas back to its original state. Plot cycle and determine the thermal efficiency of the cycle.

Detailed solution shorthand terms, formulas, laws used in the decision, the withdrawal of the calculation formula and the response.
