The absorption of water is not a chemical reaction.
No. It's a physical reaction.
When water changes state from a liquid to a solid, it is undergoing a physical change. The chemical structure of water is not altered, so no chemical changes have occurred.
Water boiling is a physical change and not a chemical reaction. In a physical reaction there is no new substance formed as is the case with chemical reactions. In boiling water there is no new substance produced.
A reaction with water (hot or cold) is a chemical reaction.
Water is not a reaction at all. If you mean to ask if a state change in water is chemical or physical, it is physical.

Its a chemical reaction :]
Chemical reaction from water
Sand and water do not react, they simply mix. This is a physical process.
No. It's a physical reaction.
During boiling the chemical composition is not changed.
No, it's a physical reaction because it is still water just in a different form.

This is a chemical reaction, a chemical change.
