STATES OF MATTERThe Four States of Matter

Four StatesSolidLiquidGasPlasma

STATES OF MATTERBased upon particle arrangementBased upon energy of particlesBased upon distance between particles

Kinetic Theory of MatterMatter is made up of particles which are in continual random motion.

STATES OF MATTERSOLIDSParticles of solids are tightly packed, vibrating about a fixed position.

Solids have a definite shape and a definite volume. Heat

STATES OF MATTERLIQUIDParticles of liquids are tightly packed, but are far enough apart to slide over one another.

Liquids have an indefinite shape and a definite volume. Heat

STATES OF MATTERGASParticles of gases are very far apart and move freely.

Gases have an indefinite shape and an indefinite volume.

Heat

PHASE CHANGES

Description of Phase ChangeTerm for Phase ChangeHeat Movement DuringPhase ChangeSolid to liquidMeltingHeat goes into the solid as it melts.Liquid to solidFreezingHeat leaves the liquid as it freezes.

STATES OF MATTERPLASMAA plasma is an ionized gas.A plasma is a very good conductor of electricity and is affected by magnetic fields.Plasmas, like gases have an indefinite shape and an indefinite volume. Plasma is the common state of matter

STATES OF MATTERSOLIDLIQUIDGASPLASMATightly packed, in a regular patternVibrate, but do not move from place to placeClose together with no regular arrangement.Vibrate, move about, and slide past each otherWell separated with no regular arrangement.Vibrate and move freely at high speedsHas no definite volume or shape and is composed of electrical charged particles
