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
    $\Delta Q_A \geq \Delta Q_B$
  • C
    $\Delta Q_A<\Delta Q_B$
  • $\Delta Q_A>\Delta Q_B$

Answer

Correct option: D.
$\Delta Q_A>\Delta Q_B$
$\Delta Q=\Delta U+\Delta W ; \Delta U$ does not depend upon path.
$\because \Delta W_A>\Delta W_B \Rightarrow \Delta Q_A>\Delta Q_B$
