states of matterMatter exists in three fundamental states (solid, liquid and gaseous), which depend on the temperature and pressure to which the matter is subjected.

amorphous solid

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

gas

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

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

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

evaporation

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

melting

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

freezing

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

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

Matter having a definite mass and volume but no shape; its atoms are relatively mobile in relation to each other. Change of a substance from a gaseous state to a liquid state; it results from cooling.

solid

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

supercooling

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