How is MATTER defined?
Write down your definition of matter here:
Technical definition of matter:
Do you know the four
states of matter?
Solids Liquid
s
GasesPlasma
Solids Solids hold their
own shape.
Solids have an ordered molecular arrangement.
Solid particles continually vibrate back and forth.
Have lower E than their liquid and gas counterparts.

Liquids Liquids take the
shape of their container.
Liquid particles are disordered.
Liquid particles slide and glide (flow) over each other.
Have medium E compared to solids and gases.

Gases Gases spread out to fill
the entire space given.
Gases are extremely disordered.
Gas particles move very fast and at random. This is regarded as flow.
Have a lot of E!

Plasma
We will not be concerned about teaching this at Coe Lake, but you might be asked…
Lightning is a plasma.
Used in fluorescent light bulbs and neon lights.
Plasma is a lot like a gas, but the particles are electrically charged.
Have extremely high E levels.

Plasmas
Which state of matter has the highest
amount of order?
Compressibility
What is compressibility?
What are some examples?
Which states of matter can be compressed?
Which states of matter have the
ability to take the shape of their
container?
have a medium density?have a very low density?have a high density?
cannot be compressed?can be compressed?
do not flow?can flow?
have a fixed shape?have the shape of their container?
have a fixed size?have the size of their
container?
Properties of S-L-G States
STATES of matter?
What would it take for matter to move from one state to another?
Energy determines the state!
Adding Energy
Add or Subtract Energy. . .
When energy is added, particles move faster!
When energy is taken away, particles move slower!
What will happen? Why?
Solid + Energy = ? When energy is added
to solids, they become liquids!
Examples?
What happens when E is taken out of a liquid?
Liquid + Energy = ? When energy is added
to liquids, they become gases!
What examples can you think of?
What is the opposite state change called?
You need to know these terms…

Changing States
There are several names for matter changing states:
State change
Phase change
Physical change
