The question pretty much sums it up. How TF is the asphalt 20-40° hotter than the air when it’s super hot?
In: 531
The concrete and the air are both being warmed by radiation from the sun.
When sun radiation hits a solid dark object like asphalt, the light is absorbed by the surface and converted into heat (heat is just how fast an object’s atoms are wiggling. The incoming light knocks into them and they wiggle more).
Air, being transparent, lets a lot of this radiation pass through rather than absorbing it and converting it to heat. So the air doesn’t warm up as much.
