Front

Define conduction.

Back

Conduction is the transfer of heat through direct contact between materials.

Front

Give an example of conduction.

Back

An example of conduction is a metal spoon getting hot when placed in a pot of boiling water.

Define convection.

Back

Convection is the transfer of heat by the movement of fluids (liquids or gases) due to differences in temperature and density.

Front

Give an example of convection.

Back

An example of convection is warm air rising and cool air sinking, creating wind.

Define radiation.

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation.

Front

Give an example of radiation.

Back

An example of radiation is feeling the warmth of the sun on your skin.

Front

What is the role of temperature in heat transfer?

Back

Temperature differences drive heat transfer; heat moves from areas of higher temperature to areas of lower temperature.

How does insulation affect heat transfer?

Back

Insulation reduces heat transfer by providing a barrier that slows down conduction, convection, and radiation.
