Transcript

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