What is Air?


Targets

At the end of this section you should be able to answer the following questions.      

1. What is air?

1.1 Of what is air made?

1.2 What are the properties of air?


You cannot see it or touch it, but somehow you do know it is there. What am I talking about? Air!

  • If someone asked you to prove that air is all around us, what would you do? 
  • How could you show them that air is everywhere around us? 
  • How would you explain what air is, and what it is made of? 

You certainly would notice if suddenly there was no air because all living things need air to breathe and live!
