Heat Transfer: Conduction, Convection, Radiation

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact of molecules or particles with each other.

Front

What is convection?

Back

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

What is an example of radiation in everyday life?

Back

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