Atoms

Everything is made up of atoms.

In solids, the particles vibrate, and when heated they receive energy and vibrate faster. At one point they start moving but are not free (they

turn into liquid).

In liquid, the particles move around, and when heated they receive energy and break free (they turn into gas).

Plasma

Exists only at high temperatures

Indefinite shape

Indefinite volume

Under influence of a magnetic field

example: Neon signs Lightning Stars

Properties of Solids

Atoms are packed (ordered)

Dense

Has a definite shape

Has a definite volume

Not very compressible

example: Ice

Properties of Liquids

Atoms are somewhat free (disordered)

(Usually) less dense than solids

Indefinite shape

Definite volume

Somewhat compressible

example: Water

Properties of Gases

Atoms are free (disordered)

Much lower density than liquids and solids

Indefinite shape

Indefinite volume

Compressible

example: Steam

Stages

Solid GasLiquid

Melting

Freezing

Boiling

Condensation

Sublimation
