Chapter 11.2, Problem 11.1WE

Interpretation Introduction

Interpretation:

The speed of Helium atom moves on average, than a Carbon dioxide molecule has to be determined.

Concept introduction:

Root mean-square speed is the parameter to measure the speed of particles in a gas. M is the molecular mass of the molecule at temperature T, root mean-square speed (${\text{u}}_{\text{rms}}$) has to be calculate using the formula

${\text{u}}_{\text{rms}}\text{=}\sqrt{\frac{\text{3RT}}{\text{M}}}$
