To change a molecule of water into a completely different substance, you would need to break the chemical bonds between the hydrogen and oxygen atoms in water (H2O) and then rearrange those atoms to form a new compound. For example, by introducing a reactive element such as sodium into the water molecule, you could create sodium hydroxide (NaOH), which is a completely different substance than water.
Chemical Change.
The chemical property of a substance relates to its ability to undergo a change. It transforms the substance into different substances.
A physical change doesn't involve the molecule composition of a substance.
A physical change doesn't change the molecule of a compound.
The transformation of water into hydrogen peroxide involves a rearrangement of atoms and the formation of new chemical bonds, resulting in a completely new substance with different properties. This chemical reaction cannot be reversed by physical means and is accompanied by the absorption or release of energy, which is characteristic of a chemical change.

When fire is produce the substance is burned and the obtained substance is having property completely different from previous one.
It is not a physical change because rust is no longer iron, but is iron oxide, a completely different substance.
The substance(s) change from one thing into something completely different, and the new substance can not seperate back into the initial substances
