1. States of Matter 3 Main states of Matter
Solid
Liquid
Gas
Different phases relate to the speed of motion of the particles
Speed of particles relates to temperature
Faster when hotter
Slower when colder

2. Solid Slowest Moving Particles Definite shape Definite volume
Particles are very close
Particles vibrate in place
Very low compressibility
(you can’t squeeze them)

3. Types of Solids Crystal Amorphous – Repeated bonding pattern
Ex: Diamond, Salt
Amorphous –
No internal shape
Ex: Glass, wax

4. Types of Solid
Heterogeneous
Has structure, but mixed
Ex: Wood, bone

5. Liquids Medium Moving Particles Not definite shape Definite volume
Particles are very close
Particles move around each other
Low compressibility

6. Viscosity Viscosity is a property of liquids
Liquids with high viscosity move slowly
Ex: Oil
Low Viscosity – Moves quickly
Ex: Water
Viscosity gets lower when liquids get hotter
