==Etymology==
[http://nordan.daynal.org/wiki/index.php?title=English#ca._1100-1500_.09THE_MIDDLE_ENGLISH_PERIOD Middle English], from Middle French liquide, from [[Latin]] liquidus, from liquēre to be fluid; akin to Latin lixa water, lye, and perhaps to Old Irish fliuch damp
*Date: [http://www.wikipedia.org/wiki/14th_Century 14th century]
==Definitions==
*1 : [[flowing]] freely like water
*2 : having the properties of a liquid : being neither [[solid]] nor [[gaseous]]
*3 a : shining and clear <large liquid eyes>
:b : being [[music]]al and free of harshness in [[sound]]
:c : smooth and unconstrained in [[Motion|movement]]
:d : articulated without [[friction]] and capable of being prolonged like a vowel <a liquid consonant>
*4 a : consisting of or capable of ready conversion into cash <liquid assets>
:b : capable of covering current liabilities quickly with current [[assets]]
==Description==
'''Liquid''' is one of the three primary [[states]] of [[matter]], with the others being [[solid]] and [[gas]]. A liquid is a [[fluid]]. Unlike a [[solid]], the [[molecules]] in a liquid have a much greater [[freedom]] to move. The [[forces]] that bind the [[molecules]] [[together]] in a solid are only temporary in a liquid, allowing a liquid to [[flow]] while a solid remains rigid.
A liquid, like a [[gas]], displays the properties of a [[fluid]]. A liquid can [[flow]], assume the shape of a container, and, if placed in a sealed container, will [[distribute]] applied [[pressure]] evenly to every [[surface]] in the container. Unlike a gas, a liquid may not always mix readily with another liquid, will not always fill every [[space]] in the container, forming its own [[surface]], and will not compress significantly, except under extremely high [[pressures]]. These properties make a liquid suitable for [[applications]] such as [http://en.wikipedia.org/wiki/Hydraulics hydraulics].
Liquid [[particles]] are bound firmly but not rigidly. They are able to move around one another freely, resulting in a [[limited]] [[degree]] of [[particle]] mobility. As the [[temperature]] increases, the increased [[vibrations]] of the [[molecules]] causes distances between the molecules to increase. When a liquid reaches its [http://en.wikipedia.org/wiki/Boiling_point boiling point], the cohesive [[forces]] that bind the molecules closely together break, and the liquid [[changes]] to its [[gaseous]] state (unless [http://en.wikipedia.org/wiki/Superheating superheating] occurs). If the [[temperature]] is decreased, the distances between the [[molecules]] become smaller. When the liquid reaches its [http://en.wikipedia.org/wiki/Melting_point freezing point] the [[molecules]] will usually lock into a very specific order, called [[crystallizing]], and the bonds between them become more rigid, changing the liquid into its [[solid]] state (unless[http://en.wikipedia.org/wiki/Supercooling supercooling] occurs].[http://en.wikipedia.org/wiki/Liquid]
