Define conduction in the context of heat transfer.

Back

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

Front

What is an example of conduction?

Back

An example of conduction is burning your hand on a hot pan.

Define convection in the context of heat transfer.

Back

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

How does the sun transfer heat to the Earth?

Back

The sun transfers heat to the Earth through radiation.

Front

What role does temperature difference play in thermal energy transfer?

Back

Temperature difference drives thermal energy transfer; heat flows from areas of higher temperature to areas of lower temperature.
