1. The Three (Four)
States of Matter

2. Words to Know
States of Matter Pressure
Solid Boyle’s Law
Liquid Charles’s Law
Gas Plasma

3. States of Matter
States of Matter: The physical forms in which
a substance can exist.
Matter consists of tiny particles called atoms
and molecules.
– They cannot be seen with out a powerful
microscope
– They are always in motion and are constantly
bumping into each other.

4. Solids
Solid: the state in which matter has a definite
shape and volume.
There are two types of solids
- Crystalline-have a very orderly, three-dimensional
arrangement of atoms or molecules. (Iron,
Diamond and Ice)
- Amorphous-are composed of atoms or molecular
that are in no particular order. (Rubber and Wax)

5. Liquid
Liquid: the state in which matter takes
the shape of its container and has a
definite volume.
Liquids can change shape, but not
volume.

6. Important properties of liquid!
Surface Tension: the force acting on the
particles surface of a liquid that causes
the liquid to form spherical drops.
Viscosity: the liquid’s resistance to flow.
(Honey has a high viscosity when
compared to water).

7. GAS!!
Gas: the state in which matter changes
in both shape and volume.
The atoms of gas move fast enough to
break away from each other.

8. Pressure
Pressure: The amount of force exerted
on a given area.

9. Laws that describe the
behavior of Gas!
Boyle’s Law: states the for a fixed
amount of gas at a constant
temperature, the volume of a gas
increases as its pressure decreases.
Weather balloons are a good example!

10. More Laws
Charles’s Law: states that for a fixed amount
of gas at a constant pressure, the volume of
the gas increases as its temperature
increases.
Example: Put a balloon into the freezer and
wait for 10 minutes.

11. Plasma
Plasma: the state of matter that does
not have a definite shape or volume
and whose particles have broken apart.
Plasmas conduct electric current.
Electric and magnetic fields effect
plasmas.

12. Plasmas Continued
Natural Plasmas are found in lightning,
fire, and the aurora borealis.
Artificial Plasmas are found in
fluorescent lights and plasma balls,
created by passing electric charges
through gases.

13. Clear As Mud???

14. Anything you write down from
the next slide, you can use on
the test! You’d better be quick
about it!
Ready, get set, GO!

Mr. Ballantyne is the best teacher ever. He is so
cool! We should all nominate him for teacher of the
year. His wife likes him to!
