Process that generates a liquid from a solid or a gas
In materials science, liquefaction is a process that generates a liquid from a solid or a gas or that generates a non-liquid phase which behaves in accordance with fluid dynamics.
It occurs both naturally and artificially. As an example of the latter, a "major commercial application of liquefaction is the liquefaction of air to allow separation of the constituents, such as oxygen, nitrogen, and the noble gases." Another is the conversion of solid coal into a liquid form usable as a substitute for liquid fuels.
In geology, soil liquefaction refers to the process by which water-saturated, unconsolidated sediments are transformed into a substance that acts like a liquid, often in an earthquake. Soil liquefaction was blamed for building collapses in the city of Palu, Indonesia in October 2018.
In a related phenomenon, liquefaction of bulk materials in cargo ships may cause a dangerous shift in the load.
Liquefaction is also used in commercial and industrial settings to refer to mechanical dissolution of a solid by mixing, grinding or blending with a liquid.
In kitchen or laboratory settings, solids may be chopped into smaller parts sometimes in combination with a liquid, for example in food preparation or laboratory use. This may be done with a blender, or liquidiser in British English.
^Some authors contend that there is a distinction between liquefaction and liquification (which is more commonly considered a misspelling), with the latter term applying only to processes involving heat. Ray Knox, David Stewart, The New Madrid Fault Finders Guide (1995), p. 36.
^"Pharmeceutical Processes: Processes of Liquefaction", The Pharmaceutical Era (April 20, 1899), Vol. 21, p. 503, stating that "[by] a process of liquefaction is meant any process the effect of which is to cause a solid or gaseous body to assume or pass into the liquid state."
