states of matter![click to hear](/images/speaker.jpg)
Matter exists in three fundamental states (solid, liquid and gaseous), which depend on the temperature and pressure to which the matter is subjected.
amorphous solid ![click to hear](/images/speaker.jpg)
Body that resembles a congealed liquid whose atoms are not ordered.
gas ![click to hear](/images/speaker.jpg)
Malleable and expandable matter whose only definable property is mass; its atoms are fully mobile with respect to each other.
crystallization ![click to hear](/images/speaker.jpg)
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](/images/speaker.jpg)
Change of a substance from a gaseous state to a liquid state; it results from cooling.
evaporation ![click to hear](/images/speaker.jpg)
Change of a substance from a liquid state to a gaseous state; it results from heating.
melting ![click to hear](/images/speaker.jpg)
Change of a substance from a solid state to a liquid state; it results from heating.
freezing ![click to hear](/images/speaker.jpg)
Change of a substance from a liquid state to a solid state; it results from cooling.
sublimation ![click to hear](/images/speaker.jpg)
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](/images/speaker.jpg)
Matter having a definite mass and volume but no shape; its atoms are relatively mobile in relation to each other.
condensation ![click to hear](/images/speaker.jpg)
Change of a substance from a gaseous state to a liquid state; it results from cooling.
solid ![click to hear](/images/speaker.jpg)
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](/images/speaker.jpg)
The process of cooling a liquid below the point at which it normally freezes (solidifies); its atoms become unstable.
