Answer 2

The correct response to this question is option B: absorbs more heat.

• Solar energy is required for the operation of solar cooking. As a result, it must concentrate sunlight.
• After that, light energy is transformed to heat energy.
• The materials utilised should be able to direct and retain heat effectively.
• For this reason, the inner wall of the solar cooker is painted black.
• The colour black can easily absorb radiation and increase the rate of heat absorption.
• This traps more heat inside the cooker and improves the solar cooker's efficiency.
• Hence, being the good conductors of heat and absorption power, the black colour is tainted.
