Chapter 12, Problem 37A

Interpretation Introduction

Interpretation:

The three assumption of kinetic molecular theory needs to be explained.

Concept introduction:

The kinetic molecular theory of gases explains macroscopic properties such as volume, pressure and temperature.

Answer to Problem 37A

There are basic assumptions of kinetic molecular theory are as follows:

(i) Gas consists of very tiny particles known as molecule.

(ii) Gas particle are perfectly elastic in nature..

(iii) The average kinetic energy of gas particle depends on absolute temperature.

Explanation of Solution

Kinetic molecular theory explains Boyle’s and Charles law. In this theory, average kinetic energy is directly proportional to temperature. In this theory, the energy is gained or lost if molecules colloid with each other. There molecules are in constant linear motion and show elastic nature.
