Chemical changes in matter New Matter is formed. Burning Rusting Cooking

CHEMICAL CHANGES

Is this a solid, a liquid, or a gas Is this a solid, a liquid, or a gas? Can you find more than one type of matter in any of the pictures?

Is this a physical change or a chemical change Is this a physical change or a chemical change? Can you find more than one physical or chemical change in the pictures?
