    I have 2 questions about Oxygen within water.

    1 Does your body use the oxygen from water at all in terms of providing the body energy? ie helps to oxygenate the blood

    2 If you boil water - do you loose some of the oxygen?

    Many thanks

    as far as i'm aware, the answer is no to both questions

    you need something that is really hungry for oxygen to break the its bonds with hydrogen + i don't think that's the case in either of your 2 hypotheses

    e.g. liquid iron will react with dampness in the air to combine with the oxygen in the water molecule, but i doubt whether haemoglobin at body temperature has the same reactivity

    I don't know about 1 but think not. We drown in water so probably can't get much if any oxygen out of it. For question 2 look up Henry's law.

    are you talking about the O that makes up part of water molecules, or are you talking about O<sub>2</sub> dissolved in water?

    i've taken it to mean the former, i.e. the O in H<sub>2</sub>O

    Boiling water reduce the amount of O2 and other gases disolved but once its cooled it will pull oxygen back from the air.
