Chapter 19, Problem 19.30E

Interpretation Introduction

Interpretation:

The relative values of ${\nu }_{\text{rms}}$, ${\nu }_{\text{most}\text{prob}}$, and $\overline{\nu }$ are to be compared. Whether ${\nu }_{\text{rms}}$, ${\nu }_{\text{most}\text{prob}}$, and $\overline{\nu }$ always would have the same relative values, or can variations in conditions like temperature or molar mass changes their relative magnitudes is to be stated.

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.
