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
There are 3 methods of heat transfer: conduction, convection and radiation. Conduction means something hot touching the pavement and getting it hot so that doesn’t happen with pavement. Convection is the hot air moving across the pavement warming it up and that’s why pavement is still pretty warm in the shade. Radiation is the biggest factor here where the direct sunlight transfers to the pavement and gets it much hotter.
