(a) A frictionless piston-cylinder device contains oxygen at -50°C and specific volume of 0.03 m'kg. The gas is heated isobarically to -20°C. Using the generalized compressibility chart, determine: () The initial pressure (in MPa), (ii) The final specific volume (in m'/kg) of the gas. I (b) A rigid tank contains 0.2 kg of propane initially at 20 bar and 200 K. The gas is cooled and the pressure drops to 15 bar. Determine the volume of the tank (in m'), and the final temperature (in K).
