Answer :
Final answer:
Heat is transferred from a radiator to the room primarily through radiation and convection; radiation directly emits heat while convection circulates warm air throughout the room. Therefore, option b) Radiation and Conduction is the correct answer.
Explanation:
Radiation and convection are the main processes by which heat is transferred through a radiator and throughout the room. Radiation is the transfer of heat in the form of electromagnetic waves, which allows the heat to radiate directly from the radiator into the room without needing a medium. Convection occurs when the heated air from the radiator rises, and cooler air moves in to replace it, setting up a circulation pattern that distributes the heat throughout the room.
Conduction, though a method of heat transfer, is less involved in the process of heating the room with a radiator. It refers to the transfer of heat through direct contact between materials, primarily between the radiator itself and the air around it.
