phase change

[′fāz ‚chānj]
(physics)
The metamorphosis of a material or mixture from one phase to another, such as gas to liquid, solid to gas.
(electronics)

phase change

(1) See phase modulation.

(2) A transition from one state to another, such as from solid to liquid or liquid to gas (see phase change cooler). It often refers to the transition between an unstructured "amorphous" atomic state and a structured "crystalline" atomic lattice (see phase change disc and phase change memory).
