Answer 1

An example of a physical change from the options you provided is **honey dissolving in tea**. In this process, the honey retains its chemical composition while mixing with the tea, which is characteristic of a physical change.

The other options involve chemical changes:
- **Sugar and oxygen reacting to produce water and carbon dioxide** involves a chemical reaction.
- **Raw egg being cooked** also involves a chemical change, as the proteins in the egg are denatured and form a different substance when cooked.
