An insulated piston-cylinder device initially contains 0.15m^3 of air at 150kPa and 22°C. The cylinder is connected to a supply line that supplies air at 700kPa and 22°C. A spring initially touches the piston without additional force. The valve is opened and the cylinder expands linearly against the spring until the volume is doubled and the final pressure is 600kPa. The valve is closed at this point. Assuming air behaves as an ideal gas with constant specific heats as given (CV = 0.718 kJ/kg.K CP= 1.005 kj/kg.K, and R=0.287kJ/kg.K) determine the following:
(a)Boundary work done.
(b)Final temperature of the air inside the cylinder.
(c)Mass of air that enters the cylinder.
