Clothes of ________ (dark, white) colors absorb heat better than clothes of light colors.

Open in App

Solution

A black object absorbs all wavelengths of light and reflects none and that's why it appears black. Consequently, black absorbs the most heat. Objects that are white, on the other hand, reflect all wavelengths of light and that's why they appear white to us, therefore absorb the least heat.
