Identify the correct statements from the following (A) The compressibility factor (Z) for an ideal gas is 1 (B) Urananium isotopes ( ²³⁵ U . and . ²³⁸ U ) are separated by converting them into UF ₆ vapours (C) Decrease in temperature increases the kinetic energy of gas molecules

Options

  1. AA, B, C
  2. BA, C only
  3. CB, C only
  4. DA, B only

Correct answer

D. A, B only

Step-by-step solution

PV = RT for an ideal gas so Z = PV RT =1 Both, ²³⁵ UF ₆ and ²³⁸ UF ₆ are separated on the basis of their molecular velocities which are different for them. Kinetic energy is directly proportional to the temperature so a decrease in temperature would decrease the kinetic energy. Thus, (A) and (B) are correct.
