Is there a word used specifically to refer to all states of water (liquid, solid and gaseous)? Obviously, "water" would technically refer to all of them, but most people would interpret "water" as the water in liquid state.
aqua (countable and uncountable, plural aquas or aquae)
(inorganic chemistry) The compound water.
I think the answer is "Matter". I learnt science in primary school. I remember that there are three states of matter: Liquid, Gas and Solid.
