Science Physics Condensed matter physics Phase transitions

Phase transitions

Physical process

Temperature at which a substance changes from liquid into vapor

Change of the physical state of matter from gas phase into liquid phase; reverse of evaporation

Critical point (thermodynamics)

Temperature and pressure point where phase boundaries disappear

Curie temperature

Temperature above which magnetic properties change

Deposition (phase transition)

Transition from a gas to a solid

Type of vaporization of a liquid that occurs from its surface; surface phenomenon

Phase transition in which a liquid turns into a solid due to a decrease in thermal energy

Process by which atoms or molecules acquire charge by gaining or losing electrons

Material phase change

Temperature at which a solid turns liquid

Metallic hydrogen

Phase of hydrogen

Ability of two substances to form a homogeneous solution when mixed regardless of concentration

Region of uniform physical properties

Chart used to show conditions at which physical phases of a substance occur

General principle in thermodynamics regarding pVT systems in equilibrium

Phase transition

Physical process of transition between basic states of matter

Plasma recombination

Process by which positive ions of a plasma capture a free (energetic) electron and combine with electrons or negative ions to form new neutral atoms (gas); exothermic reaction, meaning heat releasing

Sublimation (phase transition)

Transition of a substance directly from the solid to the gas state

Thermodynamic point where three matter phases exist

Phase transition from the liquid phase to vapor (either through evaporation or boiling)
