A mass-loaded piston/cylinder containing air is at 45 lbf/in 2, 60 F with a volume of 9

Question:

A mass-loaded piston/cylinder containing air is at 45 lbf/in 2, 60 F with a volume of 9 ft3, while at the stops V 36 ft3. An air line, 75 lbf/in 2, 1100 R, is connected by a valve. The valve is then opened until a final inside pressure of 60 lbf/in.2 is reached, at which point T = 630R. Find the air mass that enters the work, and heat transfer.
