My wife has a dark red car with (I assume it’s) aluminum roof racks that are chrome colored. The roof racks are significantly colder, like unbelievably cold compared to the roof after sitting in the sun for hours. Can someone explain this sorcery?
In: Physics
Chrome is highly reflective and has a very smooth surface, it reflects heat very well but does not adsorb it due to this it does not make for a good heat conductor, if you touch it it absorbs your heat but radiating heat does not transfer well. If you have a chrome towel warmer vs a white one it emits 1/3 less heat due to this property.
