(a) determine the final volume, in m^3
(b) the boundary work, in kJ, and
(c) the heat transfer, in kJ.
4. Carbon dioxide expands in a piston-cylinder assembly from an initial pressure of 800 kPa and a volume of 0.02 m² to a pressure of 200 kPa in a process during which the relation between pressure and volume is PV1.23 = constant. The mass of the gas is 0.35 kg. If the temperature of the gas decreases by 60°C, from an initial temperature of 95°C,
