How does heat transferred through radiation different from conduction and convection / 7622668/12287573? utm_source=registration

Conduction means the flow of heat between two objects that are in thermal contact. There is no actual mass transfer, only the thermal energy is passed from layer to layer.

Convection means transfer of heat between fluids by actual mass transfer. It occurs only in fluids.

Radiation means the emission of thermal energy in the form of electromagnetic waves by an object.
