When a car drives through a puddle of water, the change that takes place in the puddle is a physical change. Of course, chemical changes will take place in the engine of the car, but that's probably not what you are asking.
The absorption of water is not a chemical reaction.
Liquid water become gaseous water; the chemical structure is not changed.
This chemical reaction is called dehydration.
Adding salt to water is not a chemical reaction, nor is it a chemical change. When salt dissolves in water, this is an example of a physical change. Although the sodium and chlorine ions separate in the water, no chemical reaction takes place.

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.
It is not a chemical reaction.
The chemical reaction of water with sodium is a chemical change.

Yes, it is a chemical reaction.
It is a physical change.
Its a chemical reaction :]

Evaporation of a pudle is a physical change,
