• Chemical Changes
• Nuclear Changes

PHYSICAL CHANGES
· Involves changing shape or state of matter

EX: crushing, tearing, etc.

· No new substances are formed

EX: boiling water, cutting wood, smashing cars

• New substances are formed
• Properties of the matter change

• Conductivity, Acidity, Colour etc.

EX: Iron rusting, burning wood, digesting food
