The Scientific Approach to Knowledge
Classifications of matter:
by the physical states.
Strong intermolecular forces
Definite shape and volume
Can be crystalline or amorphous
Weak intermolecular forces
Indefinite shape but definite volume
Negligible intermolecular forces
No definite volume or shape
