Why do two materials, under the same weather, have different temperatures?
I have a small clue about it. For example, iron and wood supposed under the sun's radiation, and if we touch both of them, we'll notice a remarkable difference in temperatures just on the surface, or even by a near area, and that's a fact about the material itself if it reflects radiations totally (as the iron) or just a part of it (as the wood) .
That just leads to another question, if that was true then why in a cold area we found totally reversed results, because if we put the same materials in a cold area, and as the iron is the one who's going to reflect energy more than the wood, we found out that iron is actually colder than the wood?
That problem is really making me nervous and I keep asking people but none had the the convincing answer.
