Front

Define conduction in the context of heat transfer.

Back

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

Front

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.
