States of Matter click here to see animations of a solid, liquid and gas

Solids • There is a strong force of attraction between the particles • The particles are packed tightly together and the only motion is vibration. • A solid has a definite shape and volume • Solids are not compressible

Liquids • The force of attraction between the particles is somewhat strong, but not as strong as that of solids • The particles are close together, almost as close as a solid, but the particles are free to move and slide past each other • A liquid has a definite volume, but takes the shape of its container • Liquids are nearly incompressible

Gases • There is no force of attraction between the particles • The high energy particles move freely and are far apart • A gas has no definite shape and no definite volume. • Gases are very compressible
