1 2 3 Nitrogen with a mass of 1.5 kg and molar mass of 28 kg/kmol, is compressed isothermally and reversibly from 103 kPa and 20°C to 425 kPa. Calculate the work done and the heat flow during the process. Air at 101.3 kPa and 22°C has a volume of 0.0156 m³ in a cylinder and is compressed adiabatically and reversibly by a piston to 685 kPa. Calculate the final temperature, the final volume, and the work done on the air. Assume that R = 0.287 kJ/kg.K and Cp = 1.005 kJ/kg.K. A quantity of nitrogen in a perfectly insulated cylinder (so that there is no heat flow to or from the cylinder walls), expands from 355 kPa and 200°C to a volume of 0.093 m³. If the original volume were 0.034 m³, calculate the work done during expansion. Take Cy= 0.741 kJ/kg.K and y = 1.4.
