Average value of poisson's ratio for a mixture of `2` mole of each gas `A` and `B` is `1.66`, then

Options

A. Gases are mono-atomic
B. Gases are diatomic
C. Average molar heat capacity at constant volume is `4 cal`
D. Average molar heat capacity at constant `V` is `3cal`

Explanation

To solve the problem of finding the average value of Poisson's ratio for a mixture of gases A and B, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Poisson's Ratio**:
Poisson's ratio (γ) is defined as the ratio of the transverse strain to the axial strain in a material subjected to stress. For ideal gases, we can relate the average Poisson's ratio to the degrees of freedom of the gas molecules.

2. **Given Data**:
...
