(c) Black rough surface will radiate heat to large extent.

Why will black rough surface radiate heat to large extent?

  • Scientific observations have proved that maximum radiation is absorbed by black surfaces. As a result, maximum heat will also be radiated by a black surface.

  • For a shiny substance, heat absorbed will be less as maximum heat gets reflected back from a shiny object.

  • Hence, a black rough surface will absorb and radiate most heat.
