A 1 m3 tank contains air at 0.1 MPa and 20°C. A high-pressure line is connected to the tank until the pressure reaches 2 MPa. Assuming that the tank and the connecting valve are adiabatic, calculate the final temperature in the tank if the conditions in the high-pressure line remain constant at 2 MPa and 35°C. How much cooling to the tank is necessary to maintain the air temperature constant at 20°C? A 1 m3 tank contains air at 0.1 MPa and 20°C.
