Q. No.The mean free path for gas, with molecular diameter \(d\) and number density can be expressed as:
1. \(\dfrac{1}{\sqrt{2} n πd^{2}}\)
2. \(\dfrac{1}{\sqrt{2} n^{2} πd^{2}}\)
3. \(\dfrac{1}{\sqrt{2} n^{2} \pi^{2} d^{2}}\)
4. \(\dfrac{1}{\sqrt{2} n πd}\)
The mean free path of gas molecules depends on:
(\(d=\) molecular diameter)
| 1. | \(d\) | 2. | \(d^2\) |
| 3. | \(d^{-2}\) | 4. | \(d^{-1}\) |
