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.
Properties of solids
The particles are very close together because
they have a very strong attraction for each
Since they are so close, they cannot move
around. So they just vibrate in place.
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
There are Two properties in the liquid matter
1.Surface Tension-the force that act on particles on the
2.viscosity- A liquid resistance to flow

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
Properties of liquids
particles move fast enough to
overcome the attraction of some particles.

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

Did you Know that solids move slow, liquid move
medium fast, and gases move constantly.
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.
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.
Properties of gases
in a gas move quickly enough
they can break away from their attraction
for other particles.

particles can change.
liquids have viscosity.
– a liquid’s resistance to flow
viscosity of a liquid depends on the
attraction between it’s particles.
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.

Changes in Temperature
Changes in Solids
When a solid is heated, it expands and when it cools it
There are gaps between the end of the rails. In hot
weather, the rail will expand and will buckle up.
Changes in Liquids
When liquids are heated, they expand much
more than solids for a given temperature.
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
Strange fact about water!
water cooled, it expands again
when it’s temperature drops below 4
After 4 degree celcius, it will start to
expand until it reaches 0 degree
Changes in Gas
Gases expand when they are heated
Contract when they are cooled
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.
