Give an example of a change of state that happens in everday life

Freezing

Explanation:

When you freeze water in an ice tray to make ice cubes, you are taking a liquid and turning it into a solid. This creates a change of state.

Chemical changes take place on the molecular level. A chemical change produces a new substance. Examples of chemical changes include combustion (burning), cooking an egg, rusting of an iron pan, and mixing hydrochloric acid and sodium hydroxide to make salt and water.
