There are 6 lessons in this physics tutorial covering The Kinetic Theory of Gases. Ideal Gases. The tutorial starts with an introduction to The Kinetic Theory of Gases. Ideal Gases and is then followed with a list of the separate lessons, the tutorial is designed to be read in order but you can skip to a specific lesson or return to recover a specific physics lesson as required to build your physics knowledge of The Kinetic Theory of Gases. Ideal Gases. you can access all the lessons from this tutorial below.

In this Physics tutorial, you will learn:

• The definition of mole
• What is the Avogadro's number and what does it represent?
• How can we calculate the number of particles in a substance?
• What is an ideal gas?
• What is the formula of the Ideal Gas Law?
• What is the Boltzmann constant and how can we express the ideal gas law in terms of it?
• How to calculate work done by the gas in a thermodynamic process?
• How to find the work from a P - V graph?
• What are state variables and path-dependent variables?

## Introduction

How do the molecules of a gas move? Do they have a determined direction of motion or they move randomly in the space?

Is it possible to calculate the kinetic energy of each individual particle of a gas? Why? What method do we use to calculate the average kinetic energy of all particles in a gas? Which is the closest physical quantity to the average kinetic energy of particles?

What do you understand with the term "ideal"? What is an ideal gas according to your opinion?

In this tutorial, we will discuss about the behavior of gas particles in various circumstances. There are a number of factors, quantities and parameters to be considered in this regard. Therefore, the study of gases behavior is considered as an entire "theory", i.e. the kinetic theory of gases.
