Does air has mass / weight?
We know that matter is a substance that occupy space and has mass. To prove air is a matter we need to prove that air occupy space and air has mass.
Materials required:
- Three balloons
- Thread
- Ruler
- Pin
Procedure:
- Fill one balloon with air. (Balloon filled with air inflate the balloon which shows that air occupy space.
- Fill two balloons with almost equal in size.
- Tie both the balloons at both ends of the ruler.
- Have them tie another piece of string around the centre of the ruler and hang it up so that the two balloons are balanced and they do not rub against a wall.
- Take the pin and make a small hole in one balloon. When you step away, make sure the two balloons are still balanced.
Observation:
The balance changes as the air in the one balloon leaked out and the balloon became lighter.
Results:
Air occupy space as well as it has mass, this proves that air is a matter.
