Hint
|
Answer
|
It holds a definite shape and volume without a container. The particles are held very close to each other.
|
Solid
|
Able to conform to the shape of its container but retains a (nearly) constant volume independent of pressure.
|
Liquid
|
A compressible fluid. Not only will take the shape of its container but it will also expand to fill the container.
|
Gas
|
Matter under very high pressure.
|
Degenerate matter
|
a phase in which a large number of bosons all inhabit the same quantum state, in effect becoming one single wave/particle.
|
Bose-Einstein Condensate
|
Free charged particles, usually in equal numbers, such as ions and electrons.
|
Plasma
|
is a phenomenon of exactly zero electrical resistance and expulsion of magnetic fields occurring in certain materials when cooled below a characteristic critical temperature.
|
Superconductivity
|
A phase achieved by a few cryogenic liquids at extreme temperature at which they become able to flow without friction.
|
Superfluid
|
A disordered state in a system of interacting quantum spins which preserves its disorder to very low temperatures, unlike other disordered states.
|
Quantum spin liquid
|
At sufficiently high temperatures and pressures, the distinction between liquid and gas disappears.
|
Supercritical fluid
|
Similar to the 8th, it can move without friction but retains a rigid shape.
|
Supersolid
|
Atoms in this state have apparently unstable arrangements, like a liquid, but are still consistent in the overall pattern, like a solid.
|
String-net liquid
|
Similar to the 5th, but composed of fermions.
|
Fermionic Condensate
|
A solid in which atoms, molecules, or ions are packed in regular order.
|
Crystalline solid
|
Found in neutron stars. Vast gravitational pressure compresses atoms so strongly that the electrons are forced to combine with protons via inverse beta-decay, resulting in a super dense conglomeration of neutrons.
|
Neutron-degenerate matter
|
A state of where an object can have movement even at its lowest energy state.
|
Time crystals
|
A solid in which there is no far-range order of the positions of the atoms.
|
Amorphous solid
|
A state of matter that can only exist at ultra-low temperatures and consists of atoms inside of atoms.
|
Rydberg polaron
|
A solid in which the positions of the atoms have long-range order, but this is not in a repeating pattern.
|
Quasi-crystal
|
A state of matter that can exist under very high pressure while excited by super lasers.
|
Black superionic ice
|
A phase in which quarks become free and able to move independently in an ocean of gluons. May be briefly attainable in particle accelerators, or possibly inside neutron stars.
|
Quark-gluon plasma
|
A molecular solid with long-range positional order but with constituent molecules retaining rotational freedom.
|
Plastic crystal
|
Properties intermediate between liquids and crystals. Generally, able to flow like a liquid but exhibiting long-range order.
|
Liquid crystal
|
Found inside white dwarf stars. Electrons remain bound to atoms but are able to transfer to adjacent atoms.
|
Electron-degenerate matter
|
A type of quark matter that may exist inside some neutron stars close to the Tolman–Oppenheimer–Volkoff limit (approximately 2–3 solar masses). May be stable at lower energy states once formed.
|
Strange matter
