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 physical change.
Chemical changes alter molecules and therefore can not be reversed.
The water molecules are not affected by the energy (supplied by heat during boiling), and can also be reversed.
physical. no chemical bonds are being altered.
boiling water is a chemical reaction because it creates steam which is a sign of a chemical reaction, not a physical reaction

Physical
During boiling the chemical composition is not changed.
Boiling and evaporation are physical changes.
Boiling water is a physical change because it does not change the chemical composition of the water.
