$A$ 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:

  • A
    $w_1 > w_2 > w_3$
  • B
    $w_1 < w_2 < w_3$
  • C
    $w_1 = w_2 = w_3$
  • D
    $w_2 < w_3 < w_1$
