Chapter 10, Problem 10.33CP

Interpretation Introduction

(a)

Interpretation:

Whether the yellow or blue average speed is higher for the fusion gas mixture should be identified.

Concept introduction:

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

$u=\sqrt{\frac{3RT}{M}}$

Where,

• $R$ is gas constant.
• $T$ represents the temperature in kelvins.
• $M$ represents the molar mass in $\text{kg/mol}$.

Interpretation Introduction

(b)

Interpretation:

The molecular weight of blue molecules when the molecular weight of yellow is 25 should be determined.

Concept introduction:

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

$u=\sqrt{\frac{3RT}{M}}$

Where

• $R$ is gas constant.
• $T$ represents the temperature in kelvins.
• $M$ represents the molar mass in $\text{kg/mol}$.
