A certain mass of gas is carriedfrom A to B, along three paths via ACB

1.	A certain mass of gas is carriedfrom A to B, along three paths via ACB, ADB and AEB. Indicate the path along which the work done is (a) Maximum (b) Minimum.
Answer» Solution :WORK done by a GAS DEPENDS on the area enclosed between the P-V curve and the volume axis. (a) The area enclosed by curve ACB is maximum. Hence work done is maximum along path ACB. (b) The area enclosed by curve AEB is minimum. Hence work done is minimum along path AEB.
