Chapter 5, Problem 5.9PAE

Interpretation Introduction

Interpretation:

How gas exert atmospheric pressure.

Conceptual Introduction:

Gas molecules do not have fixed shape or volume. There is continuous motion between the gas molecules. They collide with each other and the walls of the container (If kept). As the molecules moves around, they bump into each other, this creates pressure. This pressure is exerted from all direction at once.

Solutions:

Due to gas molecule continuous motion and collision with each other pressure is created.

To determine:

Pressure exerted by gas in atmosphere.
