Why does the boiling temperature of water decrease when the water is under reduced pressure such as it is in a higher altitude?
At higher altitudes, there is reduced atmospheric pressure, which leads to a lower boiling point of water. This happens because with lower pressure, it is easier for water molecules to escape into the air as vapor. Therefore, at higher altitudes, water reaches its vapor pressure (boiling point) at a lower temperature than at sea level.
Why Glycerin is distilled at reduced pressure?
glycerin is distilled at reduced pressure because it has boiling point of 290 degree celsius under atmospheric pressure it slightly decomposes but under reduced pressure it distills unchanged
Does reduced vapor pressure at high altitudes causes a liquid to boil at a higher temperature?
Yes, reduced vapor pressure at high altitudes leads to a lower boiling point for liquids, not a higher one. This is because reduced pressure means there is less pressure pushing down on the liquid, making it easier for it to vaporize and boil at a lower temperature.
If the pressure in a sealed container is reduced can boiling point of a fluid be also reduced?
Yes. You can, for example, boil water at room temperature if you apply a vacuum pump to the container. However, if it was ONLY a sealed container (reduce the pressure and then take the vacuum pump away), the vapor increases the pressure and the whole thing comes to equilibrium and stops boiling.
How does atmospheric pressure affect the boiling point of matter?
Atmospheric pressure exerts pressure on the molecules of the liquid, confining them. In order to boil, the electrons must be excited, but must become hotter to overcome the pressure of the atmosphere. Therefore, pressure makes a liquid boil at a higher temperature. With a solid, the molecules are already compact together and have to be melted before they can be boiled. This does not require excitation of electrons, but it does require movement of electrons. Once the solid is melted, pressure will make it harder for the electrons to become excited.

How are speed and presure of fluid related?
The pressure exerted by a fluid is reduced as its speed increases.
What is a vacuum distillation?
When pressure is reduced the boiling point will also reduce

What happens to gas when pressure is applied to it?
the pressure and the temperature increases, and the volume is reduced.

The reduced vapor pressure at high altitudes causes a liquid to boil at a?
The higher the vapor pressure of a liquid at a given temperature, the lower the normal boiling point (i.e., the boiling point at atmospheric pressure) of the liquid.
What happens when superheated steam pressure is reduced?
steam quality increase
How does pressure affect boiling point?
An increase in pressure raises the boiling point of a liquid because it takes more energy for the liquid molecules to escape the higher atmospheric pressure above them. Conversely, decreasing the pressure lowers the boiling point as it requires less energy for the molecules to overcome the reduced atmospheric pressure.
What is the effect of decreased pressure on the boiling and freezing point?
As pressure decreases, the boiling point of water will also decrease. Backpackers camping in the high mountains are familiar with the phenomena when they get water boiling - and find that it is still only lukewarm because the atmospheric pressure at their high altitude is so low.
