Physical Changes
Physical changes are changes in materials that can be reversed.
Changes in temperature

- Example: Solid ice can be melted to make liquid water.
- Example: Water vapour can be condensed to make liquid water.
Changes of state
- Changing between solid, liquid and gas is known as a change of state.
- Changes of state are physical changes.
