Question

A given mass of gas expands from state A to state B by three paths 1, 2 and 3 shown in the figure :
If $W_1,W_2$ and $W_3$ respectively, be the work done by 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. $W_1$ < $W_2$; $W_1$ < $W_3$

Answer 1

The correct option is B $W_1$ < $W_2$ < $W_3$

A given mass of gas expands from the 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 ;$W_1<W_2<W_3$
