TS EAMCET · Physics · Kinetic Theory of Gases
Mean free path of molecules in a polyatomic gas is independent of
- A number density of the molecules
- B volume of the molecule
- C temperature of the gas
- D gas constant R
Answer & Solution
Correct Answer
(D) gas constant R
Step-by-step Solution
Detailed explanation
\(\begin{aligned} \text { Mean free path } & =\frac{1}{\sqrt{2} \pi d^2 n_V} \\ & =\frac{\mathbf{v} t}{\sqrt{2}\left(\pi d^2 \mathbf{v} t\right) n_V}=\frac{\mathbf{v} t}{\sqrt{2}(V) n_V}\end{aligned}\) where, \(d=\) size (diameter) of a molecule, \(n_V=\) number of molecules per…
