2. Solid
 Solid-The
state of matter that has a definite
volume and shape. The molecules move
slow and stay in a square shape. They
vibrate when they move.

3. Properties of solids

The particles are very close together because
they have a very strong attraction for each
other.

Since they are so close, they cannot move
around. So they just vibrate in place.

4. Solids

5. When a solid is heated it expands. For
example, when it is cool a metal bar fits inside
a metal gauge.
When the bar has been heated it will no
longer fit in the gauge or in the hole. And when
it cools down it will fit in the gauge and hole
again.

6. Liquid (cont.)

There are Two properties in the liquid matter

1.Surface Tension-the force that act on particles on the
surface

2.viscosity- A liquid resistance to flow

7. Did You Know
Did
you Know that a single helium
tank can fill about 700 balloons
.The reason that the tank can do
that is because its under pressure

8. Properties of liquids
 The
particles move fast enough to
overcome the attraction of some particles.
 The
particles slide past each other.

9. Gases

Gas-the state of Matter that has no definite shape or
volume. The molecules in the gas move so quickly and
stay far apart. The amount of space between the Gas
can change.

10. STATES OF MATTER
GAS

Particles of
gases are very
far apart and
move freely.

Gases have an
indefinite shape
and an indefinite
volume.
Heat

11. Examples of gases

Helium

Oxygen

Nitrogen

Carbon dioxide

Argon

12. Did You Know

Did you Know that solids move slow, liquid move
medium fast, and gases move constantly.

13. Changes in gases
Most liquids and solids, gases expand when they are heated
and contract when they are cooled.
If both gas and liquid undergo the same temperature rise the
gas expands about
ten times more than the liquid.

14. EXPLOSIONS


Explosion occurs when a gas is made to expand very strongly and very quickly.
It creates large forces that push on everything around.

The expansion is strong enough to break up rocks.

15. Properties of gases
 Particles
in a gas move quickly enough
they can break away from their attraction
for other particles.
 The
amount of empty space between gas
particles can change.

16. Viscosity
 All
liquids have viscosity.
 Viscosity
 The
– a liquid’s resistance to flow
viscosity of a liquid depends on the
attraction between it’s particles.

17. Example of viscosity

Ex: Water has a low viscosity, and that is why we
have rivers. Honey has a high viscosity be cause
it takes forever to flow.
Water
Honey

18. The two kinds of solids
Amorphous
Crystalline

19. PHASE CHANGES
Description of
Phase Change
Solid to
liquid
Term for Phase
Change
Melting
Liquid to
Freezing
solid
Heat Movement During
Phase Change
Heat goes into
the solid as it
melts.
Heat leaves the
liquid as it
freezes.

20. Introversion of three
states of matter

21. Changes in Temperature
Solid
Condensati
on
Liquid
Gas
Evaporation

22. Changes in Solids

When a solid is heated, it expands and when it cools it
contracts.
E.G
Railways:
There are gaps between the end of the rails. In hot
weather, the rail will expand and will buckle up.

23. Changes in Liquids

When liquids are heated, they expand much
more than solids for a given temperature.
E.G
When water get hot, it expands and rises up the
glass tube. While when the water is cool, the
level of the water in tube falls

24. Strange fact about water!
 When
water cooled, it expands again
when it’s temperature drops below 4
degree celcius.
 After 4 degree celcius, it will start to
expand until it reaches 0 degree
celcius.

25. Changes in Gas
o
Gases expand when they are heated
o
Contract when they are cooled
E.G.
Hot air balloons:
When the air in the balloon is heated, it expands and fills
the balloon. The density of the air falls and it becomes
less dense than the air around it. The surrounding area
exerts an upthrust force which is greater than the
weight on it.
