MCQ
For adiabatic process, wrong statement is
- A$dQ = 0$
- B$dU = - dW$
- C$Q =$ constant
- ✓Entropy is not constant
✓
Answer
Correct option: D.
Entropy is not constant
d
(d) For adiabatic process no heat is transferred hence $\mathrm{d} \mathrm{Q}=0$
(d) For adiabatic process no heat is transferred hence $\mathrm{d} \mathrm{Q}=0$
$\mathrm{du}=-\mathrm{d} \mathrm{w}$
As $\quad \mathrm{dQ}=0$ means $\mathrm{Q}$ is constant
