Chapter 13, Problem 51A

Interpretation Introduction

Interpretation: -This is to be explained that gases in the container exert pressure on the walls of the container.

Concept Introduction: - Kinetic molecular theory of gases explain the gaseous behavior based on experiment observations. According to this theory, gas particles are in constant random motion and collide with the walls of the container, exerting pressure.

Answer to Problem 51A

The molecules of gases are always in state of rapid random motions in all directions. The collisions are caused by the molecules on the wall’s container, exerting pressure.

Explanation of Solution

According to the kinetic theory of gases, all gases consist of molecules. These molecules are always in a state of random motion. They collide with each other as well as the walls of the container. When they collide with the walls of the container, they exert some pressure on the walls of the container.

Conclusion

Due to collision of molecules on the walls of the container, they exert pressure.
