Science Questions

Why is it often cooler to wear white clothes, rather than black clothes?

White surgaces reflect all the colors of the rainbow (ROYGBIV-red, orange, yellow, green, blue, indigo, violet), whereas black absorbs all the color in the light spectrum. The absorption of this energy causes the atoms inside the object to get excited, vibrate, and increase it's internal energy. When internal energy increases, the temperature of the object increases as well. Because black-colored materials and objects absorb more energy than lighter-colored materials, they get hotter.
