{{short description|Process that generates a liquid from a solid or a gas}}{{About|the physical process|the end of a secret|Liquidation}}In materials science, liquefactionSome 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.

Physics and chemistry

In physics and chemistry, the phase transitions from solid and gas to liquid (melting and condensation, respectively) may be referred to as liquefaction. The melting point (sometimes called liquefaction point) is the temperature and pressure at which a solid becomes a liquid. In commercial and industrial situations, the process of condensing a gas to liquid is sometimes referred to as liquefaction of gases.

Coal

Coal liquefaction is the production of liquid fuels from coal using a variety of industrial processes.

Dissolution

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.

Food preparation

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.

Irradiation

Liquefaction of silica and silicate glasses occurs on electron beam irradiation of nanosized samples in the column of transmission electron microscope.JOURNAL, Möbus, Günter, Ojovan, Michael, Cook, Stuart, Tsai, Jim, Yang, Guang, January 2010, Nano-scale quasi-melting of alkali-borosilicate glasses under electron irradiation,linkinghub.elsevier.com/retrieve/pii/S0022311509009167, Journal of Nuclear Materials, en, 396, 2–3, 264–271, 10.1016/j.jnucmat.2009.11.020, 2010JNuM..396..264M, JOURNAL, Zheng, Kun, Wang, Chengcai, Cheng, Yong-Qiang, Yue, Yonghai, Han, Xiaodong, Zhang, Ze, Shan, Zhiwei, Mao, Scott X, Ye, Miaomiao, Yin, Yadong, Ma, Evan, December 2010, Electron-beam-assisted superplastic shaping of nanoscale amorphous silica, Nature Communications, en, 1, 1, 24, 10.1038/ncomms1021, 2041-1723, 3047011, 20975693, 2010NatCo...1...24Z,

Biology

In biology, liquefaction often involves organic tissue turning into a more liquid-like state.
