Why does black always have the highest temperature?

Answer 1

White, or silver reflects light while black absorbs light. This means that the energy in the light warms up the black objects more than white ones.

If you are in a sunny country you can make a solar oven. Take a tin box and paint the outside black and leave the inside silver. Place it in the sun and put something inside it that you want to heat up. Leave it for an hour or two and you will see that it has become very hot. It can be used for cooking food.
