A mass-loaded piston/cylinder shown in Fig. P4.154, containing air, is at 300 kPa, 17◦C with a volume of 0.25 m3, while at the stops V = 1 m³. An air line, 500 kPa, 600 K, is connected by a valve that is then opened until a final inside pressure of 400 kPa is reached, at which point T = 350 K. Find the air mass that enters, the work, and the heat transfer.
