1. The States of Matter
Mod.H U.1 L.5

2. What is the Matter?
States of matter – Physical forms in which matter can exist
Matter – made up of tiny particles – atoms, molecules

3. Kinetic Theory of Matter
States that matter is made of tiny particles (atoms or molecules), which are in constant and random motion.
Proof – Brownian Motion
Explains different states of matter and properties

4. State is determined by…
Motion of particles
Speed of particles
Energy content
Distance apart
Amount of attractive forces between particles

5. 1. Solids - 2 Categories:
Crystalline – Orderly 3-dimensional repeating arrangement of particles in rows- e.g. salt, ice, diamonds

6. 2nd type …
Amorphous – Particles in no particular order or pattern -e.g. wax, rubber, glass

7. Compare

8. Properties of Solids Has definite shape Has definite volume
Particles very close to each other
Very strong attraction between particle
Particles vibrate in place
Not easily compressed

9. 2. Liquids- 2 important properties:
Surface tension – A Force….

11. 2. Viscosity – A liquid’s resistance to flow. Which flows faster
2. Viscosity – A liquid’s resistance to flow. Which flows faster? Honey, water, syrup?

12. Liquids used in hydraulic brakes.

13. Properties of Liquids Has no definite shape Has definite volume
Particles close to each other
No definite arrangement
Weaker attraction between particles, than in solids
Particles move around
Are more compressible

14. 3. Gases Are also a fluid! Has no definite shape
Has no definite volume
Particles far apart from each other
Weak forces of attraction between particles
Particles possess more energy
Particles move around freely
Are most compressible

16. 4. Plasma No definite shape No definite volume
Particles are broken apart or ionized
Gases at very high temperature
e.g. lightening, fire, the stars, aurora borealis, florescent bulbs, plasma ball 

17. 5th State of Matter? Bose-Einstein Condensate
What is it?
Find out.
Write a short paragraph.
Due next class!

18. 6th State of Matter? 7th?? More???
Fermionic Condensate - A superfluid phase formed by special particles, at very low temperatures
What about….
Liquid Crystals - ??
