(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.

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

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

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

an intermetallic compound

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

(physics) the rule which states that the number of degrees of freedom in a system at equilibrium equals the number of components minus the number of phases plus 2

An electronic circuit which changes the phase of a signal by 180°; used in the input stage of a push-pull amplifier.

an electronic circuit that causes the phase angle of a modulated wave to vary in accordance with the modulating signal

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