Thermal Energy Transfer

Heat & Thermal Energy Transfer

Use the provided sheet to fill in the missing information for your notes.

Multiple Choice

Objects do not contain HEAT. Heat is actually the TRANSFER of energy, and it always moves from the ______ object to the ______ object.

• cooler ; warmer

• warmer ; cooler

Multiple Choice

Convection works by transferring energy through the movement of a ______ or a liquid.

• solid

• gas

Multiple Choice

TRUE or FALSE: Wind is a good example of CONVECTION. When the sun heats the air near the ground, that air rises. Colder air that had been at a higher altitude sinks. When this happens, we get wind.

• True

• False

Multiple Choice

In order for conduction to work, one object/substance must ______ another object/substance.

• be close to

  (but not touch)

• touch

• be larger than

Multiple Choice

TRUE or FALSE:

Because radiation travels in the form of waves (it is RADIANT energy), it does NOT need to use a medium (matter) to move its energy.

• True

  (radiant energy doesn't require a medium)

• False

  (radiant energy must vibrate matter to travel)

• convection

Multiple Choice

Which form of transfer is taking place here?

• convection

• conduction

Multiple Choice

Which form of energy transfer is taking place here?

• conduction

• convection

• radiation

Multiple Choice

TRUE or FALSE: Refrigerators are constantly working to move the warm thermal energy in the room INTO the inside of the refrigerator.

• True

• False

Open Ended

If you grab a metal handrail that is very cold, heat moves from ________ to _______

Open Ended

Choose either conduction, convection, or radiation, and give a real world example.
