matter

2. The 3 States of Matter
O State of Matter- the physical forms in which
a substance exists.
O There are 3 states of matter.
O Solids
O Liquids
O Gases

3. A. Solids
O Solid- the state of matter that has a definite
shape & volume.
O A solids shape and volume stay the same.

4. Solids (cont.)
O Particles are very close together.
O They have a strong attraction for each other.
O The particles vibrate.

5. Examples of Solids
O Wood
O Humans
O Computers
O Marbles
O Weights

6. B. Liquids
O Liquid- the state of matter that has a
definite volume, but takes on the shape of
its container.
O Particles move fast enough to overcome the
attraction between some of the particles.
O Particles slide past each other.
O Liquids easily change shape.
O Liquids don’t easily change
volume.

7. Liquids (cont.)
O Ex: if you have a glass of milk how can you
change the shape? How can you change
the milks volume?
O All liquids have surface tension.
O Surface tension- a force that holds the
particles together.
O Surface tension (ST) causes some liquids to
form spherical drops.

8. Liquids (cont.)
O Different liquids have different ST.
O Ex: gasoline, has low ST and forms flat
drops.
O All liquids have viscosity.

9. 1. Viscosity
O Viscosity- a liquids resistance to flow
Low viscosity High viscosity

10. Examples of Liquids
O Water
O Apple juice
O Soda
O Kool-aid
O Milk

11. C. Gases
O Gas- the state of matter that has no shape
or volume.
O One small helium tank can fill almost 700
balloons.
O How is this possible?
O The tank is under pressure.

12. Gases (cont.)
O Particles in a gas move quickly, so they can
break away from their attraction for other
particles.
O The amount of empty space between gas
particles can change.

13. Example
Helium tank
Helium balloon
A helium tank holds more gas particles and they are closer
together, but in a balloon they are much farther apart and they
have much more room to move around

14. Examples of Gases
O Carbon Dioxide
O Oxygen
O Water Vapor
O Hydrogen
O Helium

15. Examples
O These are the particles of each of the states
of matter below.
