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 $w_{3}$ respectively are be the works done by the gas along three paths, then

Options:

Answer:

Solution:

Work is equal to area under $P - V$ graph (when P is plotted along y-axis). As area under graph 3 is maximum and area under graph 1 is minimum, so $w_{3}$ is maximum and $w_{1}$ is minimum.
So $w_{1} < w_{2} < w_{3}$
