1 Review Conductors move energy rapidly. Insulators move it slowly.
If you don’t want the temp. to change, STOP Energy from flowing.

2 Review Metals are good conductors due to the properties of the atoms that make up the metal. Metal atoms do not hold onto their outermost electrons very stongly; move freely about. Non-metals---Electrons do not move about!

3 More Ways to Transfer Thermal Energy Convection & Radiation
Light carries energy, which will make the sensing sheet warmer. Pattern of flashlight been can be seen. 90% of the energy arrives in the form of (invisible) infrared radiation.

4 Candle Convection The candle is surrounded by air, which is NoT a good thermal conductor, but it is converting chemical energy into thermal energy Why does the hot air float upward?

5 Transforming Kinetic Energy to Thermal Energy

6 Transforming Mechanical Energy to Thermal Energy
Rub a surface with a pencil eraser for a few seconds, Place the sensing sheet over the region, What effect does erasing have?
