Chapter 5, Problem 82E

Interpretation Introduction

Interpretation:Root mean square velocities of ${\text{CH}}_4$ and ${\text{N}}_2$ molecules at $273\text{ K}$ and $546\text{ K}$ is to be calculated.

Concept introduction:Root mean square velocity is square root of average particles velocities. It is denoted by $u_{\text{rms}}$ . Expression for $u_{\text{rms}}$ is as follows:

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

Where,

• $R$ is gas constant.
• $T$ is temperature of gas.
• $M$ is molecular weight.
