The Pressure-Volume diagram shows six curved paths that can be followed by the gas (connected by vertical paths). Which two of them should be part of a closed cycle if the net work done by the gas is to be its maximum positive value?
Options:
Answer:
D
Solution:
Work done in expansion is positive and in compression is negative.
Maximum positive net work: expand along the highest-pressure path (c) and compress back along the lowest-pressure path (e) - cycle ce.
