As the pressure in a vessel containing water is reduced with a vacuum pump it begins to boil at some point but will it continue to boil if the vessel is sealed after it begins to boil?

If the vacuum pump is on, the water will continue to boil. If the vacuum pump is off as the vessel is sealed, the boiling will stop at a point of equilibrium.


Vacuum boiling water?

vacuum is measured in inches of mercury. sea level is zero. water will boil at 212F. as negative pressure or elevation increases the boiling temp. of water decreases. if you had a pressure reading of 29.7 in" of mercury the water will boil at 192F. if you had a pressure reading of 10 in" of mercury water will boil at 32F
