Why is the boiling point of a substance at low pressure lower than the boiling point at standard pressure?

At low pressure, less energy is required for molecules to escape the liquid phase to become gaseous. Conversely, at high pressure, the boiling point is increased.

Does raising the elevation of a bowl of water lower the boiling point for that water?
As the air pressure drops the boiling point of water (or any substance) will also drop. The higher your altitude the lower the air pressure.
The temp of boiling water in Celsius?
That depends a lot on the pressure - at higher altitudes (less pressure), the boiling point is lower. At standard pressure (1 atm.), the answer is 100 degree Celsius.
Why altitude affects boiling point?
Ya ........ if you have an egg on the top of high mountain the altitude and less air density causes lower boiling points and when you get higher it reduces the boiling point of the water and it is due to atmospheric pressure.Boiling is directly proportional to atmospheric pressure which becomes lower when we go above the sea level example mountainous areas.

What effcet does altitude have on boiling point of water?
Higher altitude decreases the boiling point of water. Boiling point is defined as the point at which the vapour pressure of the substance above the liquid is equal to the external atmospheric pressure. Since the external atmospheric pressure is lower at higher altitudes, a lower vapour pressure of water is required for water to boil and therefore a lower temperature is required to achieve the desired vapour pressure.
How does abnormally low pressure affect the boiling point of a compound?
lower pressure means a lower boiling point.
What is the effect of pressure on boiling?
Lowering the pressure the boiling point is also lower.
What is the relationship between presssure and the boiling point of Liquids?
Boiling point is nothing but point at which liquid starts changing from liquid state to vapor state. liquid changes to vapor when vapor pressure equal to surrounding pressure. so if surrounding pressure is less boiling point is less and boiling point is high if surrounding pressure is high this point is on view of pressure
Does Increasing the pressure of a liquid lower its boiling point?
The boiling point of a liquid increases when atmospheric pressure is increased.
What is the boiling tempuatures of water?
Water boils at 100 degrees Celsius or 212 degrees Fahrenheit under standard conditions at sea level (at one atmosphere of pressure).The boiling point of water and any other substance depends on the atmospheric pressure, which changes with elevation. At higher altitudes, the pressure is lower, and so water boils at a lower temperature. If the barometric pressure is not at the standard value, the boiling point will be different. For example, water boils at 72 degrees Celsius on Mount Everest.See the Related Questions links to see how atmospheric pressure and elevation affect the boiling point of water.At 1 atmosphere water boils at:100 oC;373 K; or212 Fahrenheit
How does altitude effect boiling points?
The higher the pressure, the higher the boiling point. Boiling occurs when the atmospheric pressure equals the vapor pressure. So, at higher altitudes where the atmospheric pressure is lower, the vapor pressure is also lower which in turn creates a lower boiling point which causes foods to have to cook longer.
What 2 factors affect the boiling point of water?
Pressure & Temperature :) Apex
The conversion of a liquid to a gas below the boiling point?
A liquid can convert to a gas at a temperature below the boiling point because the boiling point is recognized to be a property at standard pressure. At a lower pressure a liquid may boil off at a temperature much lower than the standard boiling point.
