7. States of Matter
Chapter 8

8. Today’s Goals: Recognize that all matter consists of atoms.
Compare the particle arrangement and type of particle motion associated with different states of matter.

9. Definite shape and volume
Particles are very close
Particles have a strong attraction
Changes shape but not volume
Particles slide past each other
Overcome some of the attraction
Changes shape and volume
Particles move fast.
Less attraction between particles

11. Which state is this?

12. All About Solids… Crystalline (diamonds, ice)
Amorphous (glass, rubber, wax)

13. All About Liquids… Liquids have unique characteristics.
Surface Tension: a force that acts on the surface of particles (water drops)
Viscosity: the resistance to flow
(Honey has a higher viscosity than water.)

14. All About Gases:
Gas will spread out to fill the container.
