| Choose the correct answer from the options given below: |
A
(A)-(I), (B)-(IV), (C)-(III), (D)-(II)
B
(A)-(I), (B)-(III), (C)-(IV), (D)-(II)
C
(A)-(IV), (B)-(III), (C)-(II), (D)-(I)
D
(A)-(IV), (B)-(II), (C)-(I), (D)-(III)
Answer
(A)-(I), (B)-(III), (C)-(IV), (D)-(II)
Explanation
Solution
Monoatomic gases possess only translational degrees of freedom. So, option (I) matches with (A).
Polyatomic gases have translational and rotational degrees of freedom. So, option (II) matches with (D).
Rigid diatomic gases have translational, rotational and vibrational degrees of freedom. So, option (III) matches with (B).
Non-rigid diatomic gases possess translational, rotational and vibrational degrees of freedom. So, option (IV) matches with (C).
