liquéfaction

Liquéfaction refers to the process by which a substance transitions from a solid or gaseous state to a liquid state. This physical transformation occurs when matter gains sufficient energy to overcome intermolecular forces while maintaining molecular cohesion typical of liquids.

In the context of cryogenics and industrial applications, liquefaction commonly describes the conversion of gases into

Liquéfaction also occurs naturally during geological events. Soil liquefaction happens when saturated, loose soils lose strength

The reverse process of liquefaction is vaporization or solidification, depending on whether the liquid transitions to

Industrial liquefaction processes employ various technologies including heat exchangers, compressors, and expansion turbines. The Linde process

In food science, liquefaction describes enzymatic breakdown of solid materials into liquid form, such as during

The energy requirements for liquefaction vary significantly among substances. Helium, for instance, requires extremely low temperatures
