An ideal gas with a constant temperature specific heat capacity of 29.2 kJ/kmol pressure of 4.6 MPa with an irreversible process and from the temperature of 640 K, the pressure of 4.6 MPa and the path in the figure to the temperature of 318 K (from 1 point to 2 point, 2
from point 3 to point and finally from point 3 to point 4) by following
references In the entropy of the ideal gas as a result of the process performed by following this path
calculate the change that occurred.
