Webb7 apr. 2024 · Boiling commences when the vapor pressure of a liquid or solution equals the external or applied pressure (often the atmospheric pressure). Thus, if the applied pressure is reduced, the boiling point of the liquid decreases. This behavior occurs because a lower vapor pressure is necessary for boiling, which can be achieved at a lower temperature. WebbEvaporation is a simple process of heat exchange where a few of the liquid molecules gain energy and liberate. On the other hand, boiling involves reaching a certain temperature …
