Lesson 1 thermal energy Presentation Transcript

  • 1. Thermal Energy
    • Lesson 1
    • How is thermal energy transferred
  • 2.
    • Measure of kinetic energy of molecules
    • Thermometer
    • Fahrenheit
    • Celsius
    • Kelvin
    TEMPERATURE
  • 3.
    • Total kinetic and potential energy in a substance.
    • Thermal energy determines how warm a substance feels.
    • Warm water has more thermal energy than cool water.
    Thermal Energy
  • 4.
    • Thermal energy always moves from warmer to cooler objects.
    • Heat is the result of molecules vibrating quickly.
    • Heat is moving energy.
    HEAT
  • 5.
    • The transfer of heat by direct contact between objects or particles.
    • During conduction the particles in substances do not move, energy is passed as the particles vibrate and bump against one another.
    Conduction
  • 6.
    • Heat transferred through space as waves
    • EXAMPLE: The sun’s rays causing a sunburn.
    Radiation
  • 7.
    • Heat transferred by the movement of molecules within a substance.
    • Movement occurs from warmer areas to cooler areas.
    Convection
  • 8.
    • The movement of a substance that is caused by differences in temperature and density.
    • EXAMPLES: wind boiling water
    • NATURE WANTS
    • EVERYTHING TO BALANCE ! !
    Convection Current
  • 9.
    • Conductors are materials that transfer heat easily.
    • Examples: metals like copper and gold
    Conductors
  • 10.
    • An insulator is a material that does not transfer heat easily.
    • Examples:
    • liquids and gases
    • A jacket
    Insulators
