Q. Which is the correct statement
A) For an isothermal change $PV =$ Constant
B) In an isothermal process the change in internal energy must be equal to the work done
C) For an adiabatic change $\frac{P_{2}}{P_{1}} = \left( \frac{V_{2}}{V_{1}} \right)^{\gamma}$, where $\gamma$ is the ratio of specific heats
D) In an adiabatic process work done must be equal to the heat entering the system
Explanation
(a) Since $PV = RT$ and $T =$ constant
$\therefore PV =$ constant
