Air, initially at 85 kPa, 900K and occupying a volume of 0.15 m3, undergoes two processes. The air is compressed isothermally until the volume is halved. Then it undergoes a constant-pressure process until the volume is halved again.
Assuming ideal gas behavior,
(a) sketch the process on a P-V diagram
(b) determine the total work for the two process, in kJ
(c) determine the total heat transfer for the two process, in kJ.
