Can water exist in gaseous state at 25°c?

Question

Water is generally present in liquid state at room temperature like 25 degree Celsius but  can it exist in gaseousstate at 25 degree Celsius? 

Answer 1

Can water exist in gaseous state at 25°c?

 

Yes.  This happens when the pressure is low.  Think of a vacuum - partial or complete - a liquid will boil at low pressure, forming a vapor.  A phase diagram show this because it has pressure on the left (y axis) and temperature below (x axis).  Sorry I can't copy paste one here, but search "phase diagram water" to see this visually.
