Q. Which relation is correct for isometric process
A) $\mathrm{\Delta}Q = \mathrm{\Delta}U$
B) $\mathrm{\Delta}W = \mathrm{\Delta}U$
C) $\mathrm{\Delta}Q = \mathrm{\Delta}W$
D) None of these
Explanation
(a) For isochoric process $\mathrm{\Delta}V = 0 \Rightarrow \mathrm{\Delta}W = 0$
From FLOT $\mathrm{\Delta}Q = \mathrm{\Delta}U + \mathrm{\Delta}W \Rightarrow \mathrm{\Delta}Q = \mathrm{\Delta}U$
