MCQ
Which relation is correct for isometric process
- ✓$\Delta Q=\Delta U$
- B$\Delta W=\Delta U$
- C$\Delta Q=\Delta W$
- DNone of these
✓
Answer
Correct option: A.
$\Delta Q=\Delta U$
(a) For isochoric process $\Delta V=0 \Rightarrow \Delta W=0$From FLOT $\Delta Q=\Delta U+\Delta W \Rightarrow \Delta Q=\Delta U$
