Chapter 19, Problem 19.29E

Interpretation Introduction

Interpretation:

The expression for $\overline{{\nu }^2}$ is to be determined by using the form of $G\left(\nu \right)$. The square root of the corresponding answer gives the definition of ${\nu }_{\text{rms}}$, the root-mean-square speed is to be shown.

Concept introduction:

A gas is made up of many atoms or molecules that move with very high speeds. The kinetic energy of gases is very high. Every molecule or atom present in a gas can have a different velocity. Therefore, root mean square speed, most probable velocity, and mean velocity are calculated for a gas.
