(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.

(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
