How boiling of water is a physical change?

Boiling is the process by which a liquid turns into a vapour when it is heated to its boiling point. The change from a liquid phase to a gaseous phase occurs when the vapour pressure of the liquid is equal to the atmospheric pressure exerted on the liquid.

Boiling water is an example of a physical change and not a chemical change because the water vapour still has the same molecular structure as liquid water (H2O). The water molecule does not decompose to give hydrogen and oxygen.
