A rigid tank initially contains 3 Kg of air at 500 kPa, 290K. The tank is connected by a valve to a piston-cylinder assembly oriented vertically, and initially containing 0.05 m^3 of air at 200 kPa, 290K. When the valve is opened air flows slowly into the cylinder until the tank pressure falls to 200 kPa. The weight of the piston and pressure of the atmosphere maintain a constant pressure of 200 kPa in the cylinder. Because of heat transfer the temperture of the gas remains constant at 290K during this process. Model the air in the tank and the cylinder as a closed system. Assume ideal gas behavior, and disregard kinetic or potential energy effects. Determine the following: I) The total amount of energy transfer by work (kJ) II) The total amount of energy transfer by heat (kJ)
