Certainly! Here are two examples each for a physical change and a chemical change:
Physical Change:
- Melting of Ice: When ice melts, it transitions from a solid state to a liquid state, but its chemical composition (H₂O) remains unchanged.
- Dissolving Sugar in Water: When sugar is dissolved in water, it breaks down into individual molecules, but no new substances are formed, and the sugar can be recovered by evaporating the water.
Chemical Change:
- Rusting of Iron: This process involves the reaction of iron with oxygen and moisture in the environment to form iron oxide (rust), which is a different substance.
- Burning of Wood: When wood is burned, it reacts with oxygen to produce ash, carbon dioxide, and water vapor. The original chemical structure of the wood changes completely.
