Key Concepts

States of Matter

• The three fundamental states of matter: Solid, Liquid, and Gas.

Characteristics of Each State

• Solid:

  • Defined shape and volume.
  • Particles are tightly packed, usually in a regular pattern.
  • Particles vibrate but do not move from place to place.

• Liquid:

  • Definite volume but no fixed shape; adapts to the shape of its container.
  • Particles are close together with no regular arrangement.
  • Particles move past each other, allowing liquids to flow.

• Gas:

  • Neither definite volume nor shape; fills the container it is in.
  • Particles are well separated with no regular arrangement.
  • Particles move freely at high speeds.
