A rigid, insulated tank is initially evacuated. The tank is connected with a supply line through which air ( assumed to be ideal gas with constant specific heats) passes at 1 MPa, 350 C. A valve connected with the supply line is opened and the tank is charged with air until the final pressure inside the tank reaches 1 MPa. The final temperature inside the tank.
A. Is greater than 350 C B. Is less than 350 C C. Is equal to 350 C D. may be greater than less than, or equal to 350 C, depending on the volume of the tank
