1. Radiation

2. Radiation 1) What will the evidence be for heat transfer?
Answer = thermometers should have different temperatures
2) Which thermometer will have the highest temperature after 20 minutes?
Answer = “C” – directly under the source
3) Which thermometer will have the lowest temperature after 20 minutes?
Answer = “A & E” – furthest away from source

3. Radiation 4) Describe the flow of the path of the heat transfer.
Answer = down and out (spread out)
5) Using arrows, draw the path of heat transfer.
6) Radiation – transfer of heat by waves in a “spread out” path from its source
***most heat transferred to the Earth is in the form of radiation

4. Radiation 7) Absorber = surface that absorbs radiation
Example: dark colors (black is best)
Reflector = surface that bounces off radiation
Example: white/shiny is the best
