Chapter 13.3, Problem 3RQ

Interpretation Introduction

Interpretation:

The main ideas of the kinetic molecular theory of gases needs to be explained.

Concept Introduction:

Kinetic molecular theory is constructed on hypothesis about the behavior of each particle in a gas. The various gas laws such as Boyle’s law, Charles’ law and Avogadro’s law can be explained by using this theory.

Explanation of Solution

The main ideas of the kinetic molecular theory:

1. Gases consist of very small particles.
2. The volume occupied by the gas molecules is very much less compared to the volume of the gas.
3. The particles in a gas are in constant random motion, striking with the walls of the container. The pressure exerted by the gas arises due to these collisions of particles with the walls.
4. There is no force of attraction between gas particles.
5. The average kinetic energy of gas particles increases with increase in the absolute temperature.
