  • Solids
    • Particle Arrangement: Close together in a regular pattern
    • Particle Movement: Vibrate around fixed positions
    • Relative energy of particles: Least stored energy
    • SC1
      • Liquids
        • Particle Arrangement: Close together, irregular pattern
        • Movement of Particles: Move around each other. Fill shape of container
        • Relative energy of particles: Higher than solids, lower than gasses.
      • Gases
        • Particle Arrangement: Far apart, randomly arranged.
        • Particle Movement: Fast in all directions
        • Relative energy of particles: Most stored energy
      • Stage Changes
        • Condensing: Gas to Liquid
        • Evaporating/ Boiling: Liquid to Gas
        • Freezing: Liquid to Solid
        • Deposition: Gas to solid
        • Sublimation: Solid to Gas
        • Melting: Solid to Liquid
      • During a state change:
        • Energy is transferred to or from the particles
        • Particle arrangement changed
        • Particle movement changes
      • Melting Points
        • Substance begins to freeze if energy is transferred to the surroundings
        • Substance begins to melt if energy is transferred to the particles
      • State changes are physical changes because the particles themselves are unchanged
      • Chemical reactions are chemical changes, changed by rearraning atoms
  • Melting Points
    • Substance begins to freeze if energy is transferred to the surroundings
    • Substance begins to melt if energy is transferred to the particles
  • Substance begins to boil if energy is transferred to the particles
    • Boiling Point
      • Substance begins to condense if energy is transferred to the surroundings
      • SC1
        • Liquids

        • Chemical reactions are chemical changes, changed by rearraning atoms
  • The liquid cools down unless it is heated
    • Changing from a liquid to a gas below boiling point
      • The remaining particles have less energy
      • Particles with high enough energy leave the surface of the liquid
