A given mass of a gas expands from state $A$ to $B$ by three different paths 1, 2 and 3 as shown in Figure 3.70. If $W_{1}$ , $W_{2}$ and $W_{3}$ are the work done by the gas along the three paths, then:

Options:

Answer:

Solution:

Work done by the gas is the area under the $P$ - $V$ curve. Path 3 is the highest and path 1 the lowest, so $W_{1} < W_{2} < W_{3}$ . B.
