Presentation Transcript

  1. HEAT TRANSFER Conduction, Convection and Radiation

  2. Heat Transfer The transfer of thermal energy from a heated object to a cooler one Heat transfer involves the movement of waves or molecules

  3. Radiation • Energy in the form of waves • EVERY object has temperature (thermal energy) and emits radiant energy • Radiation is why you can feel the sun's radiant energy on a sunny day

  4. Radiation

  5. Conduction • The transfer of heat through the movement of molecules • Heated molecules move from warm to cold • consider a metal bar Conduction          

  6. Conduction

  7. Convection • Transfer of heat through the mass movement of the molecules of a liquid or gas

  8. Convection

  10. Convection DRAW A PICTURE OF CONVECTION OCCURING IN THE EARTH, THE ATMOSPHERE OR THE OCEAN. EXPLAIN HOW IT HAPPENS AND THEN EXPLAIN WHAT KINDS OF BENEFITS WE EXPERIENCE BECAUSE OF IT.
