    en.wikipedia.org/wiki/List_of_states_of_matter

    Such states of matter are studied in high-energy physics. In the 20th century, increased understanding of the properties of matter resulted in the identification of many states of matter. This list includes some notable examples.

  3. State of matter - Wikipedia

    en.wikipedia.org/wiki/State_of_matter

    Forms of matter that are not composed of molecules and are organized by different forces can also be considered different states of matter. Superfluids (like Fermionic condensate) and the quark–gluon plasma are examples. In a chemical equation, the state of matter of the chemicals may be shown as (s) for solid, (l) for liquid, and (g) for gas.

  4. Bose–Einstein condensate - Wikipedia

    en.wikipedia.org/wiki/Bose–Einstein_condensate

    At one point, when the overlap becomes significant, a macroscopic number of particles condense into the ground state. In condensed matter physics, a Bose–Einstein condensate (BEC) is a state of matter that is typically formed when a gas of bosons at very low densities is cooled to temperatures very close to absolute zero, i.e., 0 K (−273.15 ...

    Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...

  6. Phase (matter) - Wikipedia

    en.wikipedia.org/wiki/Phase_(matter)

    In the physical sciences, a phase is a region of material that is chemically uniform, physically distinct, and (often) mechanically separable. In a system consisting of ice and water in a glass jar, the ice cubes are one phase, the water is a second phase, and the humid air is a third phase over the ice and water.

  7. Matter - Wikipedia

    en.wikipedia.org/wiki/Matter

    A definition of "matter" based on its physical and chemical structure is: matter is made up of atoms. [17] Such atomic matter is also sometimes termed ordinary matter. As an example, deoxyribonucleic acid molecules (DNA) are matter under this definition because they are made of atoms.

  8. Glossary of nanotechnology - Wikipedia

    en.wikipedia.org/wiki/Glossary_of_nanotechnology

    A state of matter (also called the fifth state of matter) which is typically formed when a gas of bosons at low densities is cooled to temperatures very close to absolute zero. Bottom Up Building larger objects from smaller building blocks. Nanotechnology seeks to use atoms and molecules as those building blocks. Brownian Assembly

  9. Gas - Wikipedia

    en.wikipedia.org/wiki/Gas

    Drifting smoke particles indicate the movement of the surrounding gas.. Gas is one of the four fundamental states of matter.The others are solid, liquid, and plasma. [1] A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide).
