forms in which <a href="/wiki/Matter" title="Matter">matter</a> can exist. Four states of matter are observable in everyday life: <a href="/wiki/Solid" title="Solid">solid</a>, <a href="/wiki/Liquid" title="Liquid">liquid</a>, <a href="/wiki/Gas" title="Gas">gas</a>, and <a href="/wiki/Plasma_(physics)" title="Plasma (physics)">plasma</a>. Many intermediate states are known to exist, such as <a href="/wiki/Liquid_crystal" title="Liquid crystal">liquid crystal</a>, and some states only exist under extreme conditions, such as <a href="/wiki/Bose%E2%80%93Einstein_condensate" title="Bose–Einstein condensate">Bose–Einstein condensates</a> and <a href="/wiki/Fermionic_condensate" title="Fermionic condensate">Fermionic condensates</a> (in extreme cold), <a href="/wiki/Neutron-degenerate_matter" class="mw-redirect" title="Neutron-degenerate matter">neutron-degenerate matter</a> (in extreme density), and <a href="/wiki/Quark%E2%80%93gluon_plasma" title="Quark–gluon plasma">quark–gluon plasma</a> (at extremely <a href="/wiki/High-energy_nuclear_physics" title="High-energy nuclear physics">high energy</a>). </p><p>Historically, the distinction is based on qualitative differences in properties. Matter in the solid state maintains a fixed <a href="/wiki/Volume" title="Volume">volume</a> (assuming no change in temperature or air pressure) and shape, with component particles (<a href="/wiki/Atoms" class="mw-redirect" title="Atoms">atoms</a>, <a href="/wiki/Molecules" class="mw-redirect" title="Molecules">molecules</a> or <a href="/wiki/Ions" class="mw-redirect" title="Ions">ions</a>) close together and fixed into place. Matter in the liquid state maintains a fixed volume (assuming no change in temperature or air pressure), but has a variable shape that adapts to fit its container. Its particles are still close together but move freely. Matter in the gaseous state has both variable volume and shape, adapting both to fit its container. Its particles are neither close together nor fixed in place. Matter in the plasma state has variable volume and shape, and contains neutral atoms as well as a significant number of ions and <a href="/wiki/Electron" title="Electron">electrons</a>, both of which can move around freely. </p><p>The term <i><a href="/wiki/Phase_(matter)" title="Phase (matter)">phase</a></i> is sometimes used as a <a href="/wiki/Synonym" title="Synonym">synonym</a> for state of matter, but it is possible for a single compound to form different phases that are in the same state of matter. For example, <a href="/wiki/Ice" title="Ice">ice</a> is the solid state of water, but there are multiple <a href="/wiki/Phases_of_ice" title="Phases of ice">phases of ice</a> with different <a href="/wiki/Crystal_structure" title="Crystal structure">crystal structures</a>, which are formed at different pressures and temperatures. </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Four_classical_states">Four classical states</h2></div> <div class="mw-heading mw-heading3"><h3 id="Solid">Solid</h3></div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1236090951"><div role="note" class="hatnote navigation-not-searchable">Main article: <a href="/wiki/Solid" title="Solid">Solid</a></div> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:Gif_-AtomosSolido_01.gif" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/b/ba/Gif_-AtomosSolido_01.gif/170px-Gif_-AtomosSolido_01.gif" decoding="async" width="170" height="170" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/b/ba/Gif_-AtomosSolido_01.gif/255px-Gif_-AtomosSolido_01.gif 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/b/ba/Gif_-AtomosSolido_01.gif/340px-Gif_-AtomosSolido_01.gif 2x" data-file-width="800" data-file-height="800" /></a><figcaption>Simple illustration of particles in the solid state – they are closely packed to each other.</figcaption></figure> <p>In a solid, constituent particles (ions, atoms, or molecules) are closely packed together.

Due to chemical incompatibility between the blocks, block copolymers undergo a similar phase separation. However, because the blocks are <a href="/wiki/Covalent_bond" title="Covalent bond">covalently bonded</a> to each other, they cannot demix macroscopically as water and oil can, and so instead the blocks form <a href="/wiki/Nanometer" class="mw-redirect" title="Nanometer">nanometre-sized</a> structures.

In some solids the magnetic moments on different atoms are ordered and can form a ferromagnet, an antiferromagnet or a ferrimagnet. </p><p>In a <a href="/wiki/Ferromagnetism" title="Ferromagnetism">ferromagnet</a>—for instance, solid <a href="/wiki/Iron" title="Iron">iron</a>—the magnetic moment on each atom is aligned in the same direction (within a <a href="/wiki/Magnetic_domain" title="Magnetic domain">magnetic domain</a>). If the domains are also aligned, the solid is a permanent <a href="/wiki/Magnet" title="Magnet">magnet</a>, which is magnetic even in the absence of an external <a href="/wiki/Magnetic_field" title="Magnetic field">magnetic field</a>. The <a href="/wiki/Magnetization" title="Magnetization">magnetization</a> disappears when the magnet is heated to the <a href="/wiki/Curie_point" class="mw-redirect" title="Curie point">Curie point</a>, which for iron is 768&#160;°C (1,414&#160;°F). </p><p>An <a href="/wiki/Antiferromagnetism" title="Antiferromagnetism">antiferromagnet</a> has two networks of equal and opposite magnetic moments, which cancel each other out so that the net magnetization is zero.

An example is <a href="/wiki/Magnetite" title="Magnetite">magnetite</a> (Fe<sub>3</sub>O<sub>4</sub>), which contains Fe<sup>2+</sup> and Fe<sup>3+</sup> ions with different magnetic moments. </p><p>A <a href="/wiki/Quantum_spin_liquid" title="Quantum spin liquid">quantum spin liquid</a> (QSL) is a disordered state in a system of interacting quantum spins which preserves its disorder to very low temperatures, unlike other disordered states. It is not a liquid in physical sense, but a solid whose magnetic order is inherently disordered. The name "liquid" is due to an analogy with the molecular disorder in a conventional liquid. A QSL is neither a <a href="/wiki/Ferromagnetism" title="Ferromagnetism">ferromagnet</a>, where magnetic domains are parallel, nor an <a href="/wiki/Antiferromagnetism" title="Antiferromagnetism">antiferromagnet</a>, where the magnetic domains are antiparallel; instead, the magnetic domains are randomly oriented. This can be realized e.g. by <a href="/wiki/Geometrical_frustration" title="Geometrical frustration">geometrically frustrated</a> magnetic moments that cannot point uniformly parallel or antiparallel. When cooling down and settling to a state, the domain must "choose" an orientation, but if the possible states are similar in energy, one will be chosen randomly.
