Matter

2. What Is Matter?
All living things can be divided into matter and non-matter.
Matter is something that occupies space and has mass.

3. Air is Matter? Activity 1 Fill a basin with water.
Stick a pair of tissue on a glass jar bottom.
Dip the glass jar upside down with the opening facing downward.
Take the glass jar out.
Check whether the tissue is wet or not.
If the tissue is not wet, then the space occupied by the air is letting the tissue to be dry.
Activity 2
Prepare an empty tire tube.
Weigh it. Record the initial weight.
Fill air into the tire tube using air pump.
Weigh it. Record the final weight.
If the final weight is greater than the initial, then air is prove as matter. Since it, has mass.

4. Matter = discrete particles?

5. States Of Matter

6. Diffusion
Definition : The passive movement of molecules or particles along a concentration gradient, or from regions of higher to regions of lower concentration.
Solid : May take few days to complete
Liquid : May take few hours to complete
Gas : Instantaneously

7. Brownian Movement
Definition : random moving of particles suspended in a fluid (a liquid or a gas) resulting from their bombardment by the fast-moving atoms or molecules in the gas or liquid

8. Density

9. Solid
Liquid
Gas

10. Buoyancy
Float
An object float in water when it has lesser density compare to water
Sink
An object sink in water when it has greater density compare to water

11. Gas Under High Pressure
Gas will turn to liquid when compressed under high pressure
Advantages
More matter can be stored under liquid state rather than gas state
Easier to be transported

12. Application Hot Air Balloon Submarine Transporting Timber
Ships And Boats
Buoy
