What is a white and smooth surface like?
A white and smooth surface is a poor absorber of heat and a good reflector. It reflects most of the incoming light and heat, minimizing absorption and thus remaining cooler.

A white and smooth surface is a poor absorber of heat and a good reflector. It reflects most of the incoming light and heat, minimizing absorption and thus remaining cooler.
A white and smooth surface is characterized by its ability to reflect most of the incoming light and heat, making it a poor absorber of heat. The color white reflects the majority of the light spectrum, including visible light and heat (infrared radiation), which significantly reduces the amount of heat energy absorbed by the surface. Additionally, a smooth surface enhances this reflective property by minimizing surface irregularities that could otherwise absorb more heat.
This reflective quality helps in keeping the surface cooler and is the reason why white surfaces are often used in hot climates to reduce heat absorption. For example, white-painted buildings and roofs help in reflecting sunlight, thereby lowering indoor temperatures. Thus, the correct answer is [C] Poor absorber of heat and good reflector, as these properties are typical of white and smooth surfaces.
