Is boiling water a chemical or physical process?

Answer 1

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.

Answer 2

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.

Answer 3

physical. no chemical bonds are being altered.

Answer 4

boiling water is a chemical reaction because it creates steam which is a sign of a chemical reaction, not a physical reaction

Answer 5

Boiling is a change of phase, a physical process.

Answer 6

Boiling water is a physical process because it involves a change in state from liquid to gas without any change in the chemical composition of water molecules.

Answer 7

Boiling is a physical phenomenon.
