Chapter 5, Problem 13DQ

Interpretation Introduction

Interpretation:Equal pressures of different gases $\text{A}$ and $\text{B}$ should be explained.

Concept introduction:Square root of average of square of velocities of different particles is called root mean square velocity. It is denoted by $u_{\text{rms}}$ .

Expression for root mean square velocity is as follows:

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

Where,

• $u_{\text{rms}}$ is root mean square speed.
• $R$ is universal gas constant.
• $T$ is absolute temperature of gas.
• $M$ is molar mass of gas.
