Physics Tutorial 13.7 - Pressure, Temperature and RMS Speed

There are 3 lessons in this physics tutorial covering Pressure, Temperature and RMS Speed. The tutorial starts with an introduction to Pressure, Temperature and RMS Speed 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 Pressure, Temperature and RMS Speed. you can access all the lessons from this tutorial below.

In this Physics tutorial, you will learn:

  • What is rms speed of a gas?
  • What is the relationship between pressure temperature and rms speed in a gas?
  • Why are the factors affecting the rms speed of ideal gas molecules?
  • What is the translational kinetic energy of gas particles?
  • What is mean free path of gas molecules?
  • What are the factors affecting mean free path of gas molecules?

Introduction

Can you figure out how molecules of a gas move in space? What can you say if they are limited within the walls of a closed container?

What can you say about the momentum and kinetic energy of ideal gases? What about real gases?

What kind of movements can molecules of a gas do? Do you think they can move linearly? Can they spin around themselves? Can they oscillate around fixed positions just as the springs do?

All these things and many others will be explained in this tutorial, in which a quantitative analysis of gas molecules movement is made. Therefore, many concepts explained earlier, associated with an advanced mathematical apparatus is used here to describe the physical quantities involved. This means, you may need to recall your previous knowledge obtained in mathematics in order to better understand this tutorial.
