verflüssigtes

verflüssigtes refers to something that has been liquefied. In physics and chemistry, liquefaction is the process by which a substance changes from a solid or gaseous state to a liquid state. This transformation typically occurs when the temperature of the substance is raised above its melting point (if starting from a solid) or when its pressure is increased sufficiently, often while simultaneously cooling it below its critical temperature (if starting from a gas).

The term "verflüssigtes" is the past participle of the German verb "verflüssigen," meaning to liquefy. Therefore, "verflüssigtes" describes the state of a substance after it has undergone liquefaction. For example, verflüssigtes Erdgas (LNG) is natural gas that has been cooled to a liquid state for easier storage and transportation. Similarly, verflüssigtes Kohlendioxid (liquid carbon dioxide) is carbon dioxide that has been compressed and cooled into a liquid form, used in applications like fire extinguishers and carbonated beverages.

The properties of a substance in its liquid state differ significantly from its solid or gaseous states. Liquids have a definite volume but take the shape of their container. They are generally less dense than solids and more dense than gases. The process of liquefaction requires energy input to overcome intermolecular forces holding the substance in a more rigid or dispersed state. Understanding liquefaction is crucial in various industrial processes, including refrigeration, cryogenics, and the production of many essential chemicals.
