What are the three states of water?
Water can be solid, as ice, liquid, or gaseous, as water vapour. During a change of state, the molecules remain water molecules; their arrangement and motion change.
How do ice, liquid water and water vapour differ?
In ice, molecules vibrate around ordered positions. In liquid water, they remain close together and move past one another. In vapour, they are much farther apart and move freely.
