So, I've had several people insist that a dark colored object will radiate heat faster than an identical light colored body. I do not believe this is the case. We know that dark bodies ABSORB more short wave than light colors, and thus become hotter as a result.....but that's not the issue. Let's say I take two identical in every way objects, except one is black and one is white. I heat them both to exactly 200 c. and place them both in different rooms which are 0 degrees c. Which will cool down (radiate IR) faster? I say neither, and that both will cool down at exactly the same rate. I don't see how the color of an object would affect its RADIATION of IR.? If anyone disagrees.....please explain the mechanism by which more energy will radiate from either one. Now remember, this is assuming a perfectly dark room. If it were not totally dark, I would expect the WHITE object to cool off faster, because the black object would be also simultaneously absorbing more em than the white colored one. Either way, I see zero chance that the black object cools faster.
