Ideal Gases and the Gas Laws

The concept of an ideal gas is one that perfectly fulfils the above assumptions and has the following characteristics  

3 There are no attractive or repulsive forces between the gas molecules. 

Real gases such as nitrogen and oxygen are not truly ideal, but as long as we avoid very extreme conditions of temperature and pressure, we can assume that real gases will behave as ideal gases and will follow the gas laws. 

There are three main factors that affect gases temperature, pressure and volume. 

We will look at three possible cases in which we keep one of these factors constant and see what effect changing a second factor has on the third.
