A piston-cylinder device initially contains 1 m' of nitrogen gas at 0.14 MPa and 150 °C. The nitrogen is now expanded polytropically (with n=1.2) to a state of P=0.11 MPa. a) Determine the mass of the gas. b) Determine the initial and final specific volume. b) Determine the final temperature. c) Determine the boundary work during the process. d) Plot the process on a P-V diagram.
