Overview

From Wikipedia, the free encyclopedia · Read full article · Text CC BY-SA 4.0

Solid is a state of matter in which atoms are closely packed and are difficult to move past each other. Solids resist compression, expansion, or external forces that would alter its shape, with the degree of resistance being dependent upon the specific material under consideration. Solids also always possess the least kinetic energy per atom/molecule relative to other phases or, equivalently stated, solids are formed when matter in a fluid phase is cooled below a certain temperature. This temperature is called the melting point of the substance and is an intrinsic property; i.e. independent of how much of the matter there is. The vast majority of substances, when in the solid state, can be arranged in one of a few ubiquitous structures.
