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.
[citation needed] The words quasi-solid, semisolid, and semiliquid are used interchangeably.
Quasi-solids and semisolids are sometimes described as amorphous because at the microscopic scale they have a disordered structure unlike crystalline solids.
