Heat Transfer: Conduction, Convection, and Radiation Quiz

What is conduction?

• The transfer of heat through a fluid (liquid or gas) caused by molecular motion.

• The transfer of heat from one object to another through direct contact.

• The transfer of heat energy through empty space by electromagnetic waves.

• The process of boiling water to produce steam.
