'A 1 mº rigid tank with air at 1 MPa and 400 K is connected to an airline as shown in Fig. The valve is opened and air flows into the tank until the pressure reaches 5 MPa, at which point the valve is closed and the temperature inside is 450 K. a. What is the mass of air in the tank before and after the process? b. The tank eventually cools to room temperature, 300 K. What is the pressure inside the tank then? Tank Air line
