Describe the particle structure of solids, liquids and gases in terms of the arrangement, separation and motion of the particles, and represent these states using simple particle diagrams.

• Solids: closely packed, fixed positions, vibrate in place. Liquids: closely packed, can move/slide past each other. Gases: far apart, move freely and quickly.

• Solids: far apart, move freely. Liquids: fixed positions, vibrate in place. Gases: closely packed, can move/slide past each other.
