WebIf we know the boiling point of the substance at some specific pressure (tables usually give the value under the so-called normal pressure i.e. 1013,25 hPa) and enthalpy of vaporization (molar heat of evaporation), then we can estimate the boiling point under another, selected pressure.; The relationship between pressure change and temperature … WebVacuum distillation is often used in large industrial plants as an efficient way to remove salt from ocean water, in order to produce fresh water. This is known as desalination. The ocean water is placed under a vacuum to lower its boiling point and has a heat source applied, allowing the fresh water to boil off and be condensed. WebMar 27, 2024 · 1. Generally speaking, liquid boils at the temperature, at which its saturated vapour pressure is equal the external pressure. With external pressure going down, boiling temperature goes down as well. When external pressure goes down too much, the boiling point may meat the freezing point of the liquid and the liquid freezes. password shortcut key windows 10
