is compressed isothermally until the volume is one half of the initial volume. Further, it is cooled at a constant pressure till its volume is again halved. (a) Sketch the process on p-Vand T-S planes.   (b) Determine the total work transfer for the two processes.   (c) Calculate the total heat transferred.
