No. The sidewalk is still a sidewalk. All of the same molecules are still there in the same arrangement.

∙ 14y agoSeveral reasons, for one the sidewalk is flat and acts as a better surface to directly absorb the suns energy. Second because the sidewalk a solid object it reacts to heat quicker than a substrate such as soil does.
If you were to try the same thing on a cool night. You'd find the sidewalk was colder than the surrounding grass.

∙ 9y agoLike all solid bodies, sidewalks will absorb energy from external sources like sunlight and release it later as heat. The only solid body that will not absorb heat is one that is perfectly reflective.

∙ 15y agoThe light energy from the sun, heating up/ absorbed by the usually dark material.
If the sidewalk was white, the light would reflect more and as a result wouldn't heat up so much.

∙ 10y agoWhen a sidewalk is heated, it expands. That is the reason sidewalks are made in "sections" that have small spaces between them.

∙ 12y agoDirect solar radiation heats the sidewalk, but it's not the sun's 'light' that does it.
It's the sun's heat, that comes along with the light.
