Задача 20270.

1 kmol ideal gas at a pressure of 0.1 MPa and a temperature of 300 K is heated at constant volume to a pressure of 0.2 MPa. After that, the gas isothermally expanded to the initial pressure and then compressed to isobaric initial volume. Determine the temperature of the gas for the characteristic points of the cycle and cycle efficiency.

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