Chapter 1, Problem 1B.2E

(a)

Interpretation Introduction

Interpretation:

The root-mean square speed of Helium molecule has to be calculated.

Concept Introduction:

Root mean square speed:

Root mean square speed of molecule is give as,

    $\begin{array}{l}{\text{ν}}_{\text{rms}}\text{=}{\left(\frac{\text{3RT}}{\text{M}}\right)}^{\text{1/2}}\\ \text{Where,}\\ \text{R}\text{-}\text{gas}\text{constant}\\ \text{M-}\text{molar}\text{mass}\\ \text{T-}\text{temperature}\end{array}$

(b)

Interpretation Introduction

Interpretation:

The root-mean square speed of methane molecule has to be calculated.

Concept Introduction:

Root mean square speed:

Root mean square speed of molecule is give as,

    $\begin{array}{l}{\text{ν}}_{\text{rms}}\text{=}{\left(\frac{\text{3RT}}{\text{M}}\right)}^{\text{1/2}}\\ \text{Where,}\\ \text{R}\text{-}\text{gas}\text{constant}\\ \text{M-}\text{molar}\text{mass}\\ \text{T-}\text{temperature}\end{array}$
