text: Wikipedia has a lot of information on water I think you should refine your question a little bit however  because physics of water could mean anything.\n\nThese headings would be the most helpful from the site:\nForms of water\nAstronomical position of Earth and impact on its water\n\nchemical symbol for water is h2O two part hydrogen to one parts oxygen.\n\nwater can be a solid as ice a liquid as of course water and a gas as water vapour.\n\nIn these forms the physical properties of water can change here is a great example from wiki on the phases of matter which I think would be helpful:\nhttp://en.wikipedia.org/wiki/Phases_of_matter
