States of Matter & Changing Phases

States of Matter & Changing Phases

Solids

•Particles are packed tightly together

Particles vibrate in place.

•Do not have a lot of energy

•Definite shape, mass, & volume

Liquids

Particles are able to flow across one another easily.

More energy in the particles than solids

Definite Volume & mass

Indefinite shape

Gases

Particles move freely

More energy in the particles than liquids

Indefinite shape, Volume & mass

Plasma

Particles move freely and are highly charged

More energy in the particles than gases

Think of gases with an electrical charge
