Match the List I with List II

Choose the correct answer from the options given below:

A-III, B-IV, C-I, D-II

A-II, B-IV, C-I, D-III

A-IV, B-II, C-III, D-I

A-III, B-II, C-IV, D-I

The correct answer is:

The explanation uses the equation for the heat capacity ratio, , where is the degrees of freedom of the gas. Here's how it

applies to different types of gases:
Triatomic Rigid Gas:
Degrees of freedom ( f ) = 6

Diatomic Non-Rigid Gas:
Degrees of freedom (f) = 7

Diatomic Rigid Gas:
Degrees of freedom (f) = 5

Monoatomic Gas:

Degrees of freedom ( f ) = 3

Therefore, when matching List I with List II, the correct pairing is:

A (Triatomic rigid gas) - III
B (Diatomic non-rigid gas) - IV
C (Monoatomic gas) - I
D (Diatomic rigid gas) - II
