A rigid container of volume V = 0.1 m3 contains butane at p1 = 20 MPa and T1 = 400°C. The environment is at 27°C and 0.1 MPa. The container cools down to a temperature of T2 = 50°C.

a. Find the final pressure and quality of butane.

 b. Find the heat interaction with the environment.

 c. Find the irreversibility of the process.
