no it is the molecules in the water moving fast and bumping into each other
Its a chemical reaction :]
Because it just is. Because no chemical reaction takes place when water boils. It simply changes physical form from liquid to gas.
Physical.
The absorption of water is not 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.
It is not a chemical reaction.
The chemical reaction of water with sodium is a chemical change.
This chemical reaction is called dehydration.
Yes, it is a chemical reaction.
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.
No, mixing cornstarch with water is not a chemical reaction. It is a physical change. The cornstarch particles disperse throughout the water, but no new substances are formed.
No. It is a physical process, so it technically isn't a reaction.
