(D) For an ideal gas,the equation of state is $PV = nRT$. For $1 \ mol$ of gas,$PV = RT$,therefore the compressibility factor $Z = \frac{PV}{RT} = 1$. Thus,statement $(A)$ is correct.Uranium isotopes (${ }^{235}U$ and ${ }^{238}U$) are separated by converting them into $UF_6$ vapours,which are then separated based on their different rates of diffusion (Graham's Law). Thus,statement $(B)$ is correct.Kinetic energy $(KE)$ of gas molecules is directly proportional to the absolute temperature $(T)$,given by the relation $KE = \frac{3}{2}RT$. Therefore,a decrease in temperature leads to a decrease in the kinetic energy of gas molecules. Thus,statement $(C)$ is incorrect.Therefore,statements $(A)$ and $(B)$ are correct.
