    No. Water is water (H20) whether it is frozen, liquid, or vapour.

    H-O-H molecules remains unchanged and bond between Hydrogen and Oxygen  doesn't break as boiling is a Physical change and no new substance is formed,Hence H2O is water only but called as vapour of water.

    H2O is the molecular formula for the molecule H2O.  Water is the name we give to that molecule.  phase changes don't change that molecular structure.

    It's like a bunch of balloons.

    You could have them tried together in a bunch, that's like a solid.

    Or you could let them all go, and they float far away, that's like a gas.

    But all the while they are still balloons, just spaced differently!

    Source(s): sorry if the analogy isn't perfect.

    Evaporation is a 'PHYSICAL' change, not a 'CHEMICAL' change. So evaporated water is still H2O .

    NB ; Please write in the correct formula for water which is 'H2O' .  In chemistry single letter elements are ALWAYS written as CAPITAL letters.  If an element has a two letter symbol eg Sodium(Nadium), then the first letter is a CAPITAL and the second letter is small case. Hence Sodium (Nadium) is 'Na'.

    A physical change does not alter a chemical composition. It remains H2O.

    Liquid or solid water has bonds between the H2O molecules, so it's more like H2OH2OH2OH...

    In contrast, gaseous water is separate H2O molecules.

    No. It just changes from a liquid to a gas.

    No, its composition stays the same it just stops being a liquid
