Easy MCQ +4 / -1 PYQ · JEE Mains 2023

Match List I with List II :

List I List II
(A) 3 Translational degrees of freedom (I) Monoatomic gases
(B) 3 Translational, 2 rotational degrees of freedoms (II) Polyatomic gases
(C) 3 Translational, 2 rotational and 1 vibrational degrees of freedom (III) Rigid diatomic gases
(D) 3 Translational, 3 rotational and more than one vibrational degrees of freedom (IV) Nonrigid diatomic gases

Choose the correct answer from the options given below:

  1. A (A)-(I), (B)-(III), (C)-(IV), (D)-(II) Correct answer
  2. B (A)-(IV), (B)-(III), (C)-(II), (D)-(I)
  3. C (A)-(IV), (B)-(II), (C)-(I), (D)-(III)
  4. D (A)-(I), (B)-(IV), (C)-(III), (D)-(II)

Solution

<p>Monoatomic gases possess only translational degrees of freedom. So, option (I) matches with (A).</p> <p>Polyatomic gases have translational and rotational degrees of freedom. So, option (II) matches with (D).</p> <p>Rigid diatomic gases have translational, rotational and vibrational degrees of freedom. So, option (III) matches with (B).</p> <p>Non-rigid diatomic gases possess translational, rotational and vibrational degrees of freedom. So, option (IV) matches with (C).</p>
