Answer (1)

- Chemical Change: A new substance is formed with different properties. This usually involves breaking and forming new chemical bonds.- Physical Change: The form or appearance of a substance changes, but its chemical composition remains the same. Examples: - Rusting of iron: Iron reacts with oxygen to form iron oxide (rust), a new substance.- Boiling of water: Water changes from a liquid to a gas (steam), but it's still H₂O.- Frying an egg: The proteins in the egg change structure, creating a new substance with different properties.
