Front

Define conduction.

Back

Conduction is the transfer of thermal energy through direct contact between materials.

Front

Define convection.

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids or gases).

Front

Define radiation.

Back

Radiation is the transfer of energy through electromagnetic waves, such as light.
