Chapter 6, Problem 6.21VP

Interpretation Introduction

Interpretation: The given figures depict the possible outcomes of the effusion of gases from a balloon at constant atmospheric pressure. From the given spheres, if red sphere has a greater root-mean-square speed then the image that is more accurate is to be determined.

Concept introduction: The root-mean-square speed of any gas is calculated by the formula,

$\mu =\sqrt{\frac{3\text{R}T}{M}}$

Where,

• $\mu$ is the root-mean-square speed.
• $M$ is the molar mass of gas molecule.
• $\text{R}$ is the universal gas constant.
• $T$ is the temperature.

To determine: The more accurate image that shows the effusion of gases from a balloon at constant atmospheric pressure.
