List of states of matter

States of matter are distinguished by changes within the properties of matter associated with external factors like pressure and temperature. States are usually distinguished by a discontinuity in one amongst those properties: say, raising the temperature of ice produces a transparent discontinuity at 0 °C as energy goes into natural action, rather than temperature increase. The classical states of matter are usually summarized as: solid, liquid, gas, and plasma. Within the 20th century, increased understanding of the more exotic properties of matter resulted within the identification of many additional states of matter, none of which are observed in normal conditions.

Low-energy states [ edit ]

Natural states [ edit ]

Solid : A solid holds a definite shape and volume without a container. The particles are held very close to each other. Amorphous solid : A solid in which there is no far-range order of the positions of the atoms. Crystalline solid : A solid in which atoms, molecules, or ions are packed in regular order. Plastic crystal : A molecular solid with long-range positional order but with constituent molecules retaining rotational freedom. Quasi-crystal : A solid in which the positions of the atoms have long-range order, but is not in a repeating pattern.
