MCQ
In the figure given two processes $A$ and $B$ are shown by which a thermo-dynamical system goes from initial to final state $F.$ If $\Delta {Q_A}$ and $\Delta {Q_B}$ are respectively the heats supplied to the systems then
  • A
    $\Delta {Q_A} = \Delta {Q_B}$
  • B
    $\Delta {Q_A} \ge \Delta {Q_B}$
  • C
    $\Delta {Q_A} < \Delta {Q_B}$
  • ✓
    $\Delta {Q_A} > \Delta {Q_B}$
✓

Answer

Correct option: D.
$\Delta {Q_A} > \Delta {Q_B}$
d
(d) $\Delta Q = \Delta U + \Delta W;$       $\Delta  U$ does not depend upon path.

 $\because  \Delta {W_A} > \Delta {W_B}$ ==> $\Delta {Q_A} > \Delta {Q_B}$
