crystalline solid
a solid is made up of crystals in which particles are arranged in a regular, repeating pattern
amorphous solid
a solid made up of particles that are not arranged in a regular pattern
liquid
a state of matter that has no definite shape but has a definite volume
fluid
any substance that can flow
