1. Transferring Thermal Energy
Chapter 6.2

2. 3 ways to transfer thermal energy
Conduction
Convection
Radiation

3. Conduction
Transfer of thermal energy by collisions between particles in matter
Particles are always in motion and colliding
Thermal energy transfers from objects with more KE (higher T) to objects with less
No transfer of matter

4. Solids and liquids conduct heat better than gases
(molecules are closer together to collide)

5. Convection Liquids and gases can flow and are classified as fluids
Convection transfer of thermal energy in a fluid by movement of warmer and cooler fluid from place to place
More energetic molecules move more from one place to another

6. Radiation Transfer of energy by electromagnetic waves (light)
Can travel through space (not enough matter in space for conduction and convection)

7. Conduction, Convection or Radiation
Using a heat blanket to get warm
Conduction
Lying out in the sun getting a tan.
Radiation
Putting your wet shoes on a boot dryer to dry them.
Convection
Macaroni rising and falling in a boiling pot of water
A person placing their hands over a hot burner.
