To show that air is a matter perform an activity with a balloon. Fill the balloon with water and air separately. Write the observation in your own words and the properties of a matter on the basis of your observation.
Answers
Explanation:
Blowing up a balloon involves forcing additional air particles from your lungs into the balloon. These particles hit the inside walls of the balloon creating enough air pressure to force the rubber of the balloon to expand and the balloon to inflate.
The collision of these air particles with the walls creates a high-pressure environment inside the balloon relative to the atmospheric pressure around it. This is why when a balloon is released, the high-pressure air flows out of the balloon to the low-pressure air surrounding it: "Winds blow from high to low."

Answer:
Steps:
1. Take a ballon.
2. Fill the ballon with air.
Observations:
When we fill the balon with air its size changes and it becomes bigger and biggger.
Conclusion:
From this activity we can conclude that air is a matter as it occupies space, because when it is filled in ballon its size changes as air needs space.
The properties of matter on the basis of observations are:
1. Matter occcupies space.
Note: matter has also strong force of attraction and kinetic energy between its particles , but this activity doesn't show these two properties so, writing it in on the badis of observation will be wrong.
