Question

A given mass of gas expands from the state A to the state B by three paths 1, 2 and 3 as shown in the figure. If $w_{1},w_{2}$ and $w_{3}$ respectively be the work done by the gas along three paths then

• A. $w_{1}>w_{2}>w_{3}$
• B. $w_{1} < w_{2} < w_{3}$
• C. $w_{1}=w_{2}=w_{3}$
• D. $w_{2} < w_{3} < w_{1}$

Answer 1

Answer: (B)

As greater is the area under the curve, more is the work done.
$w_{1} < w_{2} < w_{3}$
