The four properties used to describe matter
Intensive: Depends on the type of matter, not the amount present. Ex: Hardness and density.
Extensive: Depends on the amount of matter in the sample. Ex: Mass and volume.
Physical: Traits that can be observed of the actual matter. Ex: Color and hardness.
Chemical: Reactive traits of matter. Ex: combustibility and reactiveness.
The states of matter
