Step 1: Identify the given information and the question's requirements.
The question asks whether boiling water is a physical change or a chemical change. Boiling is a process where a liquid turns into a gas due to an increase in temperature.

- Physical change: A change in which no new substances are formed. The physical properties of the substance change, but its chemical composition remains the same. Examples include changes in state (such as boiling or melting), color, shape, or size. - Chemical change: A change in which one or more substances are transformed into new substances. Chemical properties change, and bonds between atoms are broken and/or formed. Examples include burning, rusting, and chemical reactions.
Final Answer
Boiling water is a physical change.
