Chapter 13, Problem 13.77P

Interpretation Introduction

Interpretation:

The temperature when ${\text{CO}}_{\text{2}}$ has average speed as that of $\text{Ne}$ molecules at $\text{125 }°\text{C}$ has to be calculated.

Concept Introduction:

In accordance with the kinetic-gas theory the relation between average speed, temperature, and molar mass is as follows:

  $u=\sqrt{\frac{3RT}{M}}$

Here

$R$ is gas constant.

$T$ represents temperature in kelvins.

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