A refrigerator door is painted dull black on the inside and shiny white on the outside. Which statement best explains why the outside is painted white, in terms of heat transfer by radiation?
- It is a poor absorber of infrared radiation, so it gains less heat from the surroundings.
- It is a good conductor of heat, so heat can escape quickly from the fridge.
- It is a good emitter of infrared radiation, so it cools the room faster.
- It is a poor conductor of heat, so no heat can enter the fridge at all.
