Scene 1

Worksheet:  Methods of Heat Transfer 
(conduction, convection, and radiation)

Define conduction: transfer of heat by direct contact between materials 
 
Define convection: transfer of heat by movement of large volumes of fluids moving to     
balance average KE (temperature)… hot rise, cool falls 
 
Define radiation: transfer of heat not requiring a medium to move it 
 
Identify the method of heat transfer that takes place in each illustration.  Some 
illustrations may show more than one form of heat transfer.

Scene 2

In each of the following situations, identify the method of heat transfer taking 
place (conduction, convection, radiation).  More than one process may be 
occurring.

1. Hot coffee is stirred with a spoon, the spoon gets hot due to _conduction_________.

2. A chair is placed several feet from a fire in a fireplace.   The fireplace has a glass screen.  The

side of the chair facing the fireplace gets warm because of __radiation_______.

3. A certain type of decorative lamp contains colored liquids. These liquids form globs that break

off and rise to the top of the liquid.  The globs rise due to ___convection_______.

4. Near the ceiling of a room the air is warmer.  The warm air rises because of __convection___.

5. A college student holds the back of his hand near an iron to see if it is hot.  Heat is transferred

6. A heater is placed under one corner of a water bed mattress.  Warm water moves throughout

the mattress because of __convection______.

7. A certain type of stainless steel cookware has a layer of copper applied to the bottom to help it

heat evenly.  The copper transfers heat to the pan by __conduction_____.

8. In a swimming pool, the water near the surface is slightly warmer.  The warm water rises

9. One end of a copper rod is placed in a flame of a Bunsen burner.  Small pieces of wax placed

along the rod melt at progressively larger distance from the flame.  Heat is transferred through

10. A house burns down.  On the house across the street, all of the vinyl siding is twisted and

warped by the heat.  The heat was transferred across the street by __radiation____.

11. Warm air over the beach rises while cooler dense air from the ocean rushes in due to

12. The metal skewer gets so hot that you drop your marshmallow in the campfire because of

13. A huge rock at the state park gets so hot during the day that you can’t sit on it from

14. You lay on that same rock at night so that you can keep warm by __conduction____.

15. A fireman feels a door and it is hot from the fire on the other side due to __radiation___.

16. The cause of weather systems on earth is ___convection___.

17. You are in the top bunk of a bunk bed and you want to turn the air conditioner on while your

friend on the bottom bunk is fine is caused by ___convection____.
