Chapter 13, Problem 13.91P

Interpretation Introduction

Interpretation:

The root mean square speed of $\text{He}$ has to be calculated and whether this is sufficient enough to make helium escape into space has to be determined.

Concept Introduction:

The relation between average speed, temperature, and molar mass is as follows:

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

Here,

$R$ is gas constant.

$T$ represents temperature in kelvins.

$M$ represents the molar mass in $\text{kg/mol}$.
