An isobaric process at a pressure of 1000 Pa from a volume of 3.00 m3 to 1.00 m3 B. An isochoric process from the previous step to a pressure of 3000 Pa C. An UNKNOWN process which forms a straight line on a PV diagram from the end of B to the beginning of A. (a) Draw the P'v' diagram of this heat engine. au ID a. q...- n.

If you are having trouble with the unknown process, you may substitute it with an isothermal process, but you will take a deduction of 0.5 points.
