sun - Why is there a temperature gradient on Earth? - Physics...
sun 88 So a metal door in the sun will transfer the heat of the visible spectrum to the interior if painted black, will reflect it back and keep the interior cooler if painted white. It is a good reason for painting roofs and walls white in hot countries. A white car is also better in hot countries for this reason ..sunwin.
I was thinking about why the poles are colder and I came out with three possible explanations. 1. The atmosphere blocks light beams coming to poles The Sun is seen only slightly over the horizon a...sunwin-zawa
I quite liked this one [archived] describing measurements on cars. It shows that things left in the sun can get significantly hotter than the surrounding air (although there are some issues with the method used, the conclusions are mostly valid), One final note - how hot things are is not the same as how hot they seem to be.
