  • States of Matter
    • Solid
      • Particles are tightly packed, touching one another
      • Regular repeating pattern
      • Vibrate about fixed positions but do not separate
      • Forces between particles are stronger than in the liquid
    • Liquid
      • Particles are close together and touching one another
      • Irregular pattern
      • Move around and slide past each other
      • Forces between particles are not as strong as in the solid
    • Gas
      • Move freely and constantly collide with each other
      • Irregular spacing between particles
      • Non-existant forces between particles
      • Particles spaced far apart
