Is boiled water a physical or chemical change?
Yes, boiling water is a physical change. This is because the chemical composition of water does not change throughout the process of boiling.
Why boiling is chemical change?
In chemical processes (reactions) new substances appear, while in physical process, like boiling no new substance appears. Both liquid and gas is the same substance (water H2O).
Why boiling water is physical change?
Boiling water is a physical change because the gaseous water produced is chemically identical to the liquid water i.e both of them have the same molecular structure of the water. Was this answer helpful?
What type of reaction is boiling water?
As one needs to supply heat energy to boil water, this chemical reaction is considered an endothermic reaction. Here the heat energy is provided, which breaks the bond of molecules/atoms in the liquid state. Hence, boiling water is an endothermic reaction.

Why is boiling not a chemical reaction?
When water is boiled, it undergoes a physical change, not a chemical change. The molecules of water don't break apart into hydrogen and oxygen. Instead, the bonds between molecules of water break, allowing them to change physically from a liquid to a gas.
