When water boils, it undergoes physical, not chemical, changes. Water molecules do not break down into hydrogen or oxygen. Instead, the bonds between the molecules of water allow it to physically change from a liquid to a gas.
Does boiled water contain oxygen?
Yes, *boiled* water contains oxygen, but the concentration is lower due to the lower volume of boiled water (heating energizes the air-water solution, the molecules inside are released, and air gases are more easily released. The molecular forces between them are much weaker than those of H2O).
Does water lose oxygen when you boil it?
Most of the dissolved oxygen is lost by the time the water reaches 75c, and boiling appears to cause little additional loss. However, the kettle is usually covered (perhaps with a small opening for mouth s vapor release).
Is it OK to drink only boiled water?

Does boiled water contain air?
Instead of air, the bubbles in a boiling pot of water are actually composed of water. That is water in its gaseous state!
What happens when water is boiled?
Boiling water kills microorganisms such as bacteria, viruses, and protozoa that can cause disease. Boiling makes tap water microbiologically safe.
Is boiled water better than tap water?
