Boil water at room temperature in a vacuum

Boil water at room temperature in a vacuum

Can water boil at room temperature?

For water molecules to escape from a liquid and become a gas they have to overcome atmospheric pressure. Ordinarily, that means that you have to heat the water up to 100 degrees Celsius, where its internal (vapor) pressure becomes 1 Atm. However if the atmospheric pressure is lowered (like in a vacuum jar) the water can boil at a much lower temperature.

Bone head the water does not boil... You are out gassing dissolved gasses. The trick only works once. If you try to "reboil" the water you just outgassed it will do nothing. Depending on the amount of vacuum temperature should lower and eventually freeze.
