Chapter 16, Problem 121A

Interpretation Introduction

Interpretation: The reason for the non-existence of ideal gas is to be found out.

Concept introduction: Ideal gases are theoretical or a hypothetical concept in which it follows certain rules.

Answer to Problem 121A

There are no ideal gas gases. For gases in order to be identified as ideal gas need to occupy zero volume and there will not be any attractive forces in between the gas molecules. No real gases obey this.

Explanation of Solution

Ideal gases are hypothetical gas molecules that show ideality. They follow some rules that are different from real gases. In the ideal gas molecules, there will not be any attractive or repulsive forces between the molecules. And also they do not take any volume. They are simply considered point particles with no volume and no attractive or repulsive forces.

Real gases are gas molecules that take volume and have attractive or repulsive forces in between the molecules. Every gas that surrounds us is non ideal in nature. So, there are no ideal gases.
