The boiling point of water is a physical property and not a chemical property because-
|
when water is heated to its boiling point, it changes into a new substance with new properties
|
|
when water is cooled to its boiling point, it changes from a solid to a liquid and has new properties
|
|
when water is heated to its boiling point, it changes from a liquid to a solid and only changes how it reacts with other substances
|
|
when water is heated to its boiling point, it changes from a liquid to a gas without changing into a new substance

Explanation:
Detailed explanation-1: -A substance’s boiling point is a physical property. For instance, when water (H2O) boils, so when it converts from a liquid to a gas or water to steam, it is still water. The chemical identity is still H2O. The chemical property hasn’t changed, only its physical property.
Detailed explanation-2: -Boiling water is a physical change because the gaseous water produced is chemically identical to the liquid water i.e both of them have the same molecular structure of the water.
