Q. A system performs work $\mathrm{\Delta}W$ when an amount of heat is $\mathrm{\Delta}Q$ added to the system, the corresponding change in the internal energy is $\mathrm{\Delta}U$. A unique function of the initial and final states (irrespective of the mode of change) is
A) $\mathrm{\Delta}Q$
B) $\mathrm{\Delta}W$
C) $\mathrm{\Delta}U\ $and$\ \mathrm{\Delta}Q$
D) $\mathrm{\Delta}U$
Explanation
(d) Change in internal energy $(\mathrm{\Delta}U)$ depends upon initial and final state of the function while $\mathrm{\Delta}Q$ and $\mathrm{\Delta}W$ are path dependent
