Chapter 19, Problem 19.21E

Interpretation Introduction

Interpretation:

The equation 19.31 is to be verified from equation 19.30.

Concept introduction:

The average squared velocity in each direction is the same. The average square velocity is given by,

$v_{\text{avg,}x}^2=\frac{kT}{m}$

Where,

• $k$ is the Boltzmann constant.

• $T$ is the temperature.

• $m$ is the mass of the body.

The average squared velocity can be calculated with the help of one dimension probability distribution.
