My engineering teacher recently told me of a process where you can freeze 
water while it's boiling (that is, if it's in a vacuum).  He said that the 
atmospheric pressure can be right so that the only energy for the water to 
draw on to boil itself is its own kinetic energy.  Therefore, it flash 
freezes.  Please explain this phenomenon to me.
