Air is contained in a piston-cylinder device at 600 kPa and 927°C, and occupies a volume of 0.8 m². The air undergoes and isothermal process until the pressure in reduced to 300 kPa. The piston is now fixed in place and not allowed to move while a heat transfer process takes place until the air reaches 27°C. (a) Sketch the P-V diagram for the combined processes. (b) For the combined processes determine the net amount of heat transfer, in kJ, and its direction (i.e. heat in or heat out).
