amorphous solid gas crystallization condensation evaporation melting freezing sublimation liquid condensation solid supercooling

amorphous solid click to hear : amorphous solid

Body that resembles a congealed liquid whose atoms are not ordered.

gas click to hear : gas

Malleable and expandable matter whose only definable property is mass; its atoms are fully mobile with respect to each other.

crystallization click to hear : crystallization

Change of a substance from an amorphous state to a crystallized state; it results from cooling, which causes the atoms to become ordered.

condensation click to hear : condensation

Change of a substance from a gaseous state to a liquid state; it results from cooling.

evaporation click to hear : evaporation

Change of a substance from a liquid state to a gaseous state; it results from heating.

melting click to hear : melting

Change of a substance from a solid state to a liquid state; it results from heating.

freezing click to hear : freezing

Change of a substance from a liquid state to a solid state; it results from cooling.

sublimation click to hear : sublimation

Change of a substance from a solid state directly to a gaseous state without passing through the liquid state; it results from heating.

liquid click to hear : liquid

Matter having a definite mass and volume but no shape; its atoms are relatively mobile in relation to each other.

condensation click to hear : condensation

Change of a substance from a gaseous state to a liquid state; it results from cooling.

solid click to hear : solid

Rigid body possessing mass, volume and a definite form; its atoms are linked to each other and are almost completely at rest.

supercooling click to hear : supercooling

The process of cooling a liquid below the point at which it normally freezes (solidifies); its atoms become unstable.
