Steam is the visible form of water in the gaseous state when you boil it.Water vapour,though,is invisible to the eye and does not require boiling the water to a hundred degrees for the conversion.A vapour is a gas state of a substance at a temperature where it can co-exist with its liquid or solid state so for a liquid or solid to become vapour it does not have to first boil.
