Question

Which of the following statements about heat energy is correct? a] White surfaces absorbs heat more than black surfaces B. Radiation of heat has nothing to do with the colour of the surface. C. Black surfaces absorbs heat better than white surface D. Red surfaces are better absorbers of heat than black surfaces.

Answer 1

Answer:

c

Explanation:

black surfaces absorbs heat better than white surfaces

Answer 2

Statement (C) is correct about heat energy.

• We know that a black body is a perfect absorber of radiations while a white body is a perfect reflector.
• It shows that radiation depends upon the color of the surface.
• Since black is the best absorber no other color can absorb better than it.
• Hence, black surfaces absorb heat better than white or any other colored surface.
