Nitrogen gas leaves a compressor at 2 MPa and 120 °C, and is collected in three different cylinders, each of volume 0.3 m3. In each case the cylinder is to be filled to a pressure of 2 MPa. Cylinder 1 is initially evacuated, cylinder 2 contains nitrogen at 0.1 MPa and 20 °C, and cylinder 3 contains nitrogen at 1 MPa and 20 °C. Find the final temperature of nitrogen in each cylinder, assuming nitrogen to be an ideal gas with a constant-pressure heat capacity of 29.3 J/molK. In each case assume the gas does not exchange heat with the cylinder walls.
