Chapter 5, Problem 5.130QP

Interpretation Introduction

Interpretation:

The Maxwell speed distribution curves of given gases has to be identified.

Concept Introduction:

A Maxwell speed distribution curve shows how many gas molecules are moving at various speeds at a given temperature. As temperature increases, more molecules move at greater speeds.

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

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