Q. 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 $\mathrm{\Delta}Q_{A}$ and $\mathrm{\Delta}Q_{B}$ are respectively the heats supplied to the systems then
A) $\mathrm{\Delta}Q_{A} = \mathrm{\Delta}Q_{B}$
B) $\mathrm{\Delta}Q_{A} \geq \mathrm{\Delta}Q_{B}$
C) $\mathrm{\Delta}Q_{A} < \mathrm{\Delta}Q_{B}$
D) $\mathrm{\Delta}Q_{A} > \mathrm{\Delta}Q_{B}$
Explanation
(d) $\mathrm{\Delta}Q = \mathrm{\Delta}U + \mathrm{\Delta}W;\mathrm{\Delta}U$ does not depend upon path
$\because\mathrm{\Delta}W_{A} > \mathrm{\Delta}W_{B} \Rightarrow \mathrm{\Delta}Q_{A} > \mathrm{\Delta}Q_{B}$
