MATTER: States

• Solids have a DEFINITE SHAPE• Solids have a DEFINITE VOLUME

• Solids have STRONG BONDS

• Liquids DON’T have a DEFINITE SHAPE• Liquids have a DEFINITE VOLUME

• Liquids have WEAK BONDS

• Gases DON’Thave a DEFINITE SHAPE• Gases DON’T have a DEFINITE VOLUME

• Gases DON’T have BONDS
