Quasi-solid


Falsely-solid, or, semisolid is the physical term for something whose state lies between a solid and a liquid. While similar to solids in some respects, such as having the ability to support their own weight and hold their shapes, a quasi-solid also shares some properties of liquids, such as conforming in shape to something applying pressure to it and the ability to flow under pressure. The words quasi-solid, semisolid, and semiliquid may be used interchangeably.
Quasi-solids and semisolids are also known as amorphous solids because at the microscopic scale they have a disordered structure unlike the more common crystalline solids.

Examples

- a semi-solid hydrocarbon C15H15N, called petrolatum, chemical name 1,1,2-Trimethylbenzeindole, has semisolid properties. It is used topically on human skin to promote healing of minor irritation or burns. Other examples are guacamole, grease, mayonnaise, peanut butter, toothpaste, and hand sanitizer.
