(physics) One of the three fundamental structural phases of matter in which the thermal mobility of molecules or atoms is strong enough to permit their free motion, significantly exceeding the cohesive force.

(physics) One of the three fundamental structural phases of matter in which the cohesive force of matter is strong enough to keep the molecules or atoms in the given positions, restraining the thermal mobility.

(astronomy) Any one of the aspects or appearances presented by the moon as seen from Earth.

(physics) The conversion of a single-phase system into a multiphase system; especially the separation of a solution into two immiscible liquids.

(physics) One of the three fundamental structural phases of matter in which the thermal mobility of molecules or atoms is comparable with the cohesiveness, having them connected but fluid in a mass.

(electricity) Differing in phase by a quarter of a cycle; two-phase.

A method of sending information by modifying (modulating) the difference in phase (fraction of a wave length) between a signal and a reference.

The homogeneous part of a heterogeneous system that consists of water or a solution in water of a substance.

an intermetallic compound

(physics) The velocity of propagation of a pure sine wave of infinite extent and infinitesimal amplitude.
