Vedclass · Answer

(B) The work done by a gas during expansion is equal to the area under the $P-V$ curve. From the given figure,the area under the curve for path $3$ is the largest,followed by path $2$,and the area under the curve for path $1$ is the smallest. Therefore,the work done follows the order $w_3 > w_2 > w_1$,which is equivalent to $w_1 < w_2 < w_3$.

$A$ given mass of gas expands from state $A$ to state $B$ by three paths $1, 2$ and $3$ as shown in the figure. If $w_1, w_2$ and $w_3$ are the work done by the gas along the three paths respectively,then:
