What are the three primary states of matter?
What are the three primary states of matter?
Solid, liquid, and gas
Properties of solids
Properties of solids
Incompressible, fixed shape/volume, high density
Properties of liquids
Properties of liquids
Take container shape, fixed volume, slightly compressible
Properties of gases
Properties of gases
Fill all available space, highly compressible, no fixed shape/volume
