  1. How many ways are there to transfer heat? How can thermal energy (heat) be transferred?

  2. Where does the heat come from? Where does the heat go? How long will the heat last?

  3. Transfer of Heat Notes 2-2-12 Heat can move 3 ways…… Any idea how? Convection! Radiation! Conduction!

  4. Convection • The transfer of heat in a gas or liquid by movement of currents. Warm air rises and cool air sinks making a current. Ex: Heat leaves a coffee cup as the currents of steam and air rise. The warmed matter (air) is being transferred.

  5. Convection currents move heated air around the Earth. Ex: Pasta rising and falling in a pot of boiling water

  6. Have you ever touched something hot? How does that happen?

  7. Conduction • The transfer of heat through matter from particle to particle. Ex: A spoon in a bowl of hot soup becomes warmer because the heat is conducted along the spoon.

  8. Conduction is most effective in solids but also happens in liquids.

  9. Radiation • Transfer of heat by electromagnetic waves moving through space. Ex: Sunlight is a form of radiation. The Sun transfers heat through 93 million miles of space.

  10. Radiation is the way air is heated. • Convection currents move the heated air around the Earth.
