In physics, to liquefy or liquify means to turn something into the liquid state. Since antiquity, people have tried to understand the behavior of matter: why unsupported objects drop to the ground, why different materials have different properties, and so forth. ... A liquid will assume the shape of its container. ...

This can be a change from a gas to a liquid (condensation), usually by cooling, or a change from a solid to a liquid (melting), usually by heating or by grinding and blending with another liquid. In the physical sciences, a phase is a set of states of a macroscopic physical system that have relatively uniform chemical composition and physical properties (i. ... Physics In physics, melting is the process of heating a solid substance to a point (called melting point) where it turns liquid. ...

Liquefaction refers in physics, chemistry, and genetic engineering to the process of condensing a gas into a liquid, while in geology and genetic engineering it refers to the process by which saturated, unconsolidated sediments are transformed into a substance that acts like a liquid. In the energy industry either liquification or occasionally liquefaction refers to reforming coal or gas into a liquid form that is economical to transport and use as fuel. Liquefaction is the process by which saturated, unconsolidated soil or sand is converted into a suspension. ... Sediment is any particulate matter that can be transported by fluid flow and which eventually is deposited as a layer of solid particles on the bed or bottom of a body of water or other liquid. ...
