Vedclass · Answer

(B) Convection is a mode of heat transfer that occurs in fluids (liquids and gases) due to the actual movement of the molecules of the medium.In the case of heating a room by a heater,the air near the heater gets warm,becomes less dense,and rises,while the cooler,denser air moves in to take its place. This continuous circulation of air,known as convection currents,heats the entire room.Heating of a copper utensil and an iron rod are examples of conduction,while heat transfer from the sun to the earth occurs via radiation.Therefore,the correct option is $B$.
