Radiation
Lower Sec Science · Secondary 2 · Medium · Radiation
A metal box is painted with a shiny white surface on the outside. Using your knowledge of heat transfer by radiation, why does this help keep the inside of the box cooler on a hot day?
- It is a poor absorber of infrared radiation, so less radiant heat is taken in.
- It is a good conductor of heat, so heat is quickly carried away.
- It is a poor conductor of heat, so no heat can enter the box at all.
- It is a good emitter of infrared radiation, so it absorbs more heat.
