(A) The compressibility factor (Z) for an ideal gas is 1
(B) Urananium isotopes \(\left({ }^{235} \mathrm{U}\right.\) and \(\left.{ }^{238} \mathrm{U}\right)\) are separated by converting them into \(\mathrm{UF}_6\) vapours
(C) Decrease in temperature increases the kinetic energy of gas molecules

  4. D A, B only
Verified Solution

Answer & Solution

Correct Answer

(D) A, B only

Step-by-step Solution

Detailed explanation

\(\mathrm{PV}=\mathrm{RT}\) for an ideal gas so \(\mathrm{Z}=\frac{\mathrm{PV}}{\mathrm{RT}}=1\) Both, \({ }^{235} \mathrm{UF}_6\) and \({ }^{238} \mathrm{UF}_6\) are separated on the basis of their molecular velocities which are different for them. Kinetic energy is directly…
