Question

fill in the chart with three examples of physical changes and three examples of chemical changes.

Explanation:

Physical changes involve alterations in physical properties (like state, shape) without new substances. Chemical changes result in new substances with different properties.

• Physical Change Examples:
• Melting of ice (solid to liquid, no new substance).
• Tearing paper (shape change, no new substance).
• Boiling water (liquid to gas, no new substance).
• Chemical Change Examples:
• Burning wood (produces ash, smoke - new substances).
• Rusting of iron (iron oxide formed - new substance).
• Digesting food (complex substances broken into simpler ones - new substances).

Answer:

Physical Change	Chemical Change
Tearing paper	Rusting of iron
Boiling water	Digesting food
