4 Methods of Heat Transfer -Conduction, Convection, No medium is required for the heat to travel. Advection: Horizontally heat transfer by advection method. Formation of Sea Breeze and Land Breeze During day time, the land gets hotter than the water in the sea. So, air on land gets heated by convection and moves up. This place is then occupied by the cold air from the sea. What Is Heat Transfer? Conduction, Convection, Radiation ... Heat can travel from one place to another in several ways. The different modes of heat transfer include: Conduction. Convection. Radiation. Meanwhile, if the temperature difference exists between the two systems, heat will find a way to transfer from the higher to the lower system. How is heat transferred? Conduction -- Convection -- Radiation Heat can be transmitted through empty space by thermal radiation often called infrared radiation. This is a type electromagnetic radiation . No mass is exchanged and no medium is required in the process of radiation. Examples of radiation is the heat from the sun, or heat released from the filament of a light bulb.
