Question

Black surfaces are better________of heat than polished surfaces

• A. absorbers
• B. reflectors
• C. transmitters
• D. None of these

Answer 1

The correct option is A absorbers

Black surfaces are better absorbers of heat than polished surface.

When heat is incident on the polished or shiny surfaces, most of the heat gets reflected. But in case of black surfaces, heat gets absorbed, there is no cause of reflection of heat. We can also say that polished surfaces are better reflectors of heat than black surfaces.
