Editing Boiling (section)

==Physics==
The boiling point of an [[Chemical element|element]] at a given pressure  is a characteristic attribute of the element. This is also true for many simple compounds including water and simple [[Alcohol (chemistry)|alcohol]]s. Once boiling has started and provided that boiling remains stable and the pressure is constant, the temperature of the boiling liquid remains constant. This attribute led to the adoption of boiling points as the definition of 100&nbsp;°C.

===Distillation===
Mixtures of volatile liquids have a boiling point specific to that mixture producing vapour with a constant mix of components - the [[constant boiling mixture]]. This attribute allows mixtures of liquids to be separated or partly separated by boiling and is best known as a means of separating [[ethanol]] from water.
