Vapourisation is an example of a physical change.

Here's the step-by-step explanation:

1. Physical and Chemical Changes: Changes in matter can be classified into two types - physical changes and chemical changes.

2. Physical Changes: A physical change is a type of change in which the form of matter is altered but one substance is not transformed into another. The original substance still maintains its properties.

3. Examples of Physical Changes: Examples of physical changes include changes in state (like melting, freezing, and boiling), changes in shape or size, and division into pieces.

4. Vapourisation: Vapourisation is a process where a substance changes from a liquid state to a gaseous state.

5. Vapourisation as a Physical Change: During vapourisation, the liquid substance is not transformed into a new substance. It simply changes its state from liquid to gas. The substance before and after vapourisation is the same, only its state has changed. Therefore, vapourisation is an example of a physical change.
