This is because boiling is caused by the liquid water turning to gas which is not influenced directly by other materials. However, once in a vacuum the pressure is so low that the water will boil at much lower temperatures.
No, because the low pressure would mean that the temperature of the water would be too low to cook the egg.
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
Vacuum
Place the container of water in a vacuum & it should start to boil at room temperature.
The water will boil (no calculations necessary, but look at a table that shows the vapor pressure of water at different temperatures.here's a link: http://en.wikipedia.org/wiki/Vapour_pressure_of_water )
Technically speaking, boiling is when the pressure inside the system is equal to that of the surroundings. That means that you can boil water at room temperature if you have a vacuum pump. If you mean just to the heat that it starts to boil at STP, then no, it doesn't. Boiling point at STP is and always will be 100 degrees Celsius.
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.
Clarification: I am wanting to know how much vacuum I need to pull to get water to boil at 150 degrees.

Vacuum
The amount of heat needed to boil water varies with the air pressure. Water in a vacuum will boil at room temperature.
Place the container of water in a vacuum & it should start to boil at room temperature.
The purpose of the vacuum in the fresh water generator it can make a 50 degrees Celsius boil the water that's why they create a
Choose a vacuum pump with a 29.75 hg that makes water boil 1 degree C. The typical boiling point of water is hundred degrees Celsius.

Roughly 16 inches before the surface starts to boil from the vacuum, this is also assuming 33 degree water, the higher the water temp the less lift will be achieved due to water's vapor pressure.
Warm sea water, in an open system, is pumped into a vacuum chamber so that it will boil, and the resultant steam will drive the electricity turbines.
in order to boil water you need to heat it, so its the same thing
