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?
