Oh, right, forgot this was a physics forum.
Technically I meant evaporated, whereas you are thinking boiling.
Water BOILS at 212F (wait, since this is a physics forum I must add that the temp at which water boils will be affected by the pressure of the water, the atmosphere, the additives, if any, in the water the alignment of Uranus and the number of jelly beans in my left pock on the 5th Tuesday of every even numbered month. The formula used to include the relative position of Pluto, but since Pluto is not really a planet the equation was changed.) .
It will evaporate at a lower temp.
Tomorrow AM look at your hot (non-boiling, under 212F) cup of coffee. That. That is STEAM.
It looks suprisingly similiar to this.
