(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.

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

an intermetallic compound

(physics, chemistry) A graph, with axes representing temperature and pressure, showing the equilibrium conditions for a given substance to be a solid, liquid or gas.

(inorganic chemistry) A series of molybdenum chalcogenide compounds, of general formula MₓMo₆X₈ (where M = a metal and X = a chalcogen), that have superconducting properties.

not in phase / out of synchronization

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

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