Because it just is.
Because no chemical reaction takes place when water boils. It simply changes physical form from liquid to gas.
During boiling the chemical composition is not changed.
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.
The salt dissolves into the water. You can undo this reaction by boiling the water so it evaporates then you will be left with just salt.
Water boiling is a physical process; also dissolving. Rusting is a chemical process (oxidation).
no, boiling is a physical change
A physical reaction, or change, is one that can be observed without changing the chemical composition of the substance. Boiling is a physical change because the substance that is boiling does not change its chemical composition. For example, water is still H2O whether it is boiling or not boiling.
When a kettle is boiling you are able to see the chemical reaction, from the stem leaving the kettle.
chemical
no it is the molecules in the water moving fast and bumping into each other
No, boiling water is a physical change, not a chemical reaction. The process involves increasing the temperature of water until it reaches its boiling point, causing the water molecules to gain enough energy to change from liquid to gas (steam).
No, a reaction with many substances is not a physical property of water. Physical properties of water include its boiling point, density, and color, whereas the ability to undergo reactions with different substances is a chemical property.
Physical, as it may be reversed through condensation.
