Phases of Matter

States of Matter Solid Liquid Gas Plasma

Sodium as Solid, Liquid, Gas

Kinetic Molecular Theory all matter is composed of small particles these particles are in constant motion

Solid Definite volume Definite shape Particles closely packed together Strong attractive forces Very low KE

Liquid Definite volume, but takes the shape its container Particles close together and mobile Low KE

Gas No definite volume No definite shape Particles spaced far apart Attractive forces much weaker High KE

Microscopic view of a gas Microscopic view of a liquid Microscopic view of a solid

Plasma Gas-like Very high KE Collide with enough energy to break into charged particles
