What happens to water vapor in a vacuum?
When we keep water in vacuum, water will not evaporate to produce vapour. But water vapour to rise up, there must be a medium to push down. As there is no medium in vacuum, water vapour will not rise up. Water evaporates at all temperature but not in vacuum.
Does evaporation occur in vacuum?
Not only does evaporation occur in vacuum, it (non-linearly) lowers the temperature needed to reach the vapor pressure needed to occur.
At what temperature does water evaporate in a vacuum?
>Water Boiling Temperature vs Pressure Vacuum Chart Table

| 194 | 90 | 9.23 |
Does water flow in vacuum?
No, water cannot travel through a vacuum. The much lower pressure would drastically lower it’s boiling point and it would turn to steam.
Can liquid water exist in a vacuum?
Liquids will boil whenever the surrounding pressure is less than the vapor pressure of that material. All materials have a vapor pressure, and in a perfect vacuum, the surrounding pressure would be zero. This means that no liquids could remain a liquid in a perfect vacuum.
How long does it take to evaporate water in a vacuum?
The entire volume of water will be sucked up into the vacuum, and will fly out of the container. It will not be instantaneous, but this would probably occur within two seconds.

Why drying is done in vacuum place?
Vacuum drying is generally used for the drying of substances which are hygroscopic and heat sensitive, and is based on the principle of creating a vacuum to decrease the chamber pressure below the vapor pressure of the water, causing it to boil. The result is a significantly increased drying rate of the product.
Do all liquids evaporate in a vacuum?
No liquid can be completely stable in a vacuum, since all liquids have some non-zero vapour pressure, and so will evaporate at some rate. However some liquids have an exceptionally low vapour pressure, and so can be used in a vacuum.
