Physics Tutorial 13.9 - Gas Laws

[ 19 Votes ]

There are 4 lessons in this physics tutorial covering Gas Laws. The tutorial starts with an introduction to Gas Laws 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 Gas Laws. you can access all the lessons from this tutorial below.

In this Physics tutorial, you will learn:

  • What is the relationship between pressure and volume of an ideal gas at constant temperature?
  • What is the relationship between pressure and temperature of an ideal gas at constant volume?
  • What is the relationship between volume and temperature of an ideal gas at constant pressure?
  • What is the relationship between volume and amount of an ideal gas at constant temperature and pressure?
  • What does the P - V graph represent in each case?


In the previous tutorials, we have pointed out the existence of the three thermodynamic parameters: pressure, volume and temperature. Now we will discuss more in detail what happens when we manipulate any of these variables or keep them constant.
