Chapter 19, Problem 19.38E

Interpretation Introduction

Interpretation:

The equation $19.41$ is to be derived.

Concept introduction:

The mean distance traveled by the same particle between two consecutive collisions is termed as mean free path. The value of the mean free path of a gas depends on the pressure and temperature of the system. The mean free path of gas is represented as,

$\lambda =\frac{V}{\sqrt{2}\pi N{d}^2}$

Where,

• $d$ collision diameter of a gas.

• $N$ represents the number of particles in the given volume.

• $V$ represents the volume.
