== Boiling ==

'''Boiling''' (/ˈbɔɪlɪŋ/) is a phase transition from the liquid phase to the gas phase that occurs at or above the boiling point of a liquid. The boiling point of a liquid varies depending upon the surrounding environmental pressure. 

=== Etymology ===

The term "boiling" comes from the Old English ''bylcan'', meaning "to bubble up".

* [[Liquid]]: A state of matter that has a definite volume but no fixed shape.
* [[Gas]]: A state of matter consisting of particles with sufficient energy to overcome intermolecular forces.
* [[Boiling point]]: The temperature at which a liquid boils and turns to vapor.
* [[Pressure]]: The force applied perpendicular to the surface of an object per unit area over which that force is distributed.
* [[Vaporization]]: The phase transition from the liquid phase to vapor, which can occur from either the surface of the liquid or from the liquid-state within the liquid.
