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 $\mathrm{d} \mathrm{Q}=0$

$\mathrm{du}=-\mathrm{d} \mathrm{w}$

As $\quad \mathrm{dQ}=0$ means $\mathrm{Q}$ is constant
