Chapter 13.1, Problem 6LC

Interpretation Introduction

Interpretation:

The relation between the average kinetic energy and Kelvin temperature is to be determined.

Concept Introduction :

The kinetic theory of gases is a theoretical model, to characterize the molecular makeup of the gas. It is a theory that describes the states of matter and is based on the idea that all matter is made up of small particles that are constantly moving.

Answer to Problem 6LC

The oxygen molecules collide with each other and with the wall of the container and transfer energy.

Explanation of Solution

The behavior of gases is described by the kinetic molecular theory. The main assumptions of the kinetic molecular theory are as follows:

• There is no energy gain or loss when molecules collide.
• In a container, the space occupied by gas molecules is extremely minimal.
• These molecules always move at a constant speed.
• Particles collide with one another, and the container walls cause the gas pressure to build up.

So as per the kinetic molecular theory, when oxygen is sealed in a container, the molecules of the gas collide with one another and exchange energy with other oxygen molecules or the container wall.
