11.Thermodynamics
easy
For adiabatic process, wrong statement is
A
$dQ = 0$
B
$dU = - dW$
C
$Q =$ constant
D
Entropy is not constant
Solution
(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
