Air, initially at 150 kpa, 500k and occupying a volume of .02m^3, undergoes two processes. first, the air undergoes a constant-pressure process until the volume is doubled. then, it's expanded isothermally until the volume is doubled 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.
