The document discusses the three states of matter: solids, liquids, and gases. It describes their key properties - solids have a definite shape and volume, liquids take the shape of their container but have a definite volume, and gases have no definite shape or volume. Examples are given for each state, such as desks for solids, water and milk for liquids, and oxygen and helium for gases. The document also covers concepts like surface tension in liquids and Charles' Law regarding how temperature affects a gas's volume.

Three states of
matter

2. A. States of matter
States of matter- The physical forms in
which a substance exist.
 -Solids, Liquids, Gases.


3. B. Solids
Solid- The state of matter that has a
definite shape and volume.
 Particles are very close together and
have a very strong attraction.
 A solids particles are very slow and
compacted together.
 Even though they move very slowly they
are never stopped. All particles
constantly vibrate.


4. B. Solids cont.
Ex.
- Desk
- Walls
- People
- Paper
- Cups


5. C. Liquids
Liquids- The state of matter that has a
definite volume but takes the same
shape of its container.
 These particles move just enough for
some particles to separate. They over
come the attraction.
 All liquids have surface tension.


6. C. Liquids cont.
Surface tension- A force that holds
together particles at the surface of a
liquid.
 The higher surface tension the more it
bubbles over.
 Viscosity- A liquids resistance to flow
 All liquids have viscosity.


7. C. Liquids cont.
Ex.
- When you pour water into a glass it
adapts to the shape of the cup. The SAME
liquid can be use in different containers
and they will have a different shape.
- Sprite - Tea
- Milk
- Blood

8. D. Gases
Gas- The state of matter that has no
definite shape or volume.
 These particles break free of their
attraction very easily because they
move so fast.
 Temperature can change the gases
volume.


9. D. Gases cont.
Ex.
- Farts
- Oxygen
- Hydrogen
- Smoke
- Helium
The helium

10. 1. Charles’s Law
Charles’s law states temperature
changes with volume.
 When the temperature goes down, the
volume goes down.
 When temperature goes up so does
volume.
