Chapter 6, Problem 6.18VP

Interpretation Introduction

Interpretation: A container with a pinhole leak is given to contain a mixture of the elements highlighted in figure $\text{P}6.15$. The element which has the smallest root-mean-square speed 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 element which has the smallest root-mean-square speed.
