Water Boiling point Temperature

What is the boiling point of water under negative pressure?
Your question is really confusing! Boiling occurs whenever the environmental pressure is less than or equal to the saturated vapor pressure of water! For specific suggestions, see \"Principles of Chemical Engineering\"
The condition for boiling is the simultaneous and extensive vaporization at both the surface and within the liquid, which occurs under heating conditions. If it is merely a flashing condition, where air is forced out of the water in a closed container, causing the pressure to drop below the saturated vapor pressure at that temperature, then most of the vaporization occurs on the surface of the liquid; very little vaporization takes place inside the liquid, and boiling does not occur
Different pressures (calculated from negative atmospheric pressure) correspond to different boiling points of water, which can be found in tables of steam property parameters.
