[5] 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.
[7] In a related phenomenon, liquefaction of bulk materials in cargo ships may cause a dangerous shift in the load.
[8][9] In physics and chemistry, the phase transitions from solid and gas to liquid (melting and condensation, respectively) may be referred to as liquefaction.
In commercial and industrial situations, the process of condensing a gas to liquid is sometimes referred to as liquefaction of gases.
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.
