From gcsescience.com; "Heat can be transferred by conduction only in solids." Q. Doesn't conduction take place directly prior to convection (when a radiator heats up a room)? If my cold hand came into contact with the warm radiator this would cause conduction; why isn't it the same for the cold air coming into contact with the warm radiator? Q. Is it the case that 'radiator' isn't the most sensible term for the heating device in question given that, although it does radiate heat, it mainly heats up the room by causing convection?
