Conduction
Lower Sec Science · Secondary 2 · Medium · Conduction
The walls of a picnic cooler are filled with polystyrene foam. Why does this material help to reduce heat gain by conduction?
- It contains many air pockets and air is a poor conductor of heat.
- It is shiny, so it reflects all the infrared radiation.
- It is heavy, so heat cannot move through it easily.
- It is black, so it absorbs all the surrounding heat.
