MicroScale

  • Thermometer is put into warm water
  • Particles created random motion and friction
  • Alcohol/water solution rises up the thermometer

MacroScale

  • Thermometer placed in warm or cool water
  • Cool water: solution sinks to show low temp.
  • Warm water: solution rises to show higher temp.
