  4. Physical Change • A change in matter from one for m to another • Melting • Crushing a can • Freezing water • Sanding wood • Dissolving sugar into water

  5. Chemical Properties • A property of matter that describes a substance’s ability to participate in chemical reactions • Flammability • Reactivity

  6. Chemical Changes • When a substance changes into an entirely new substance • Souring milk • Rust • Tarnishing • Burning
