Thanks for the insightful answer! Anyone know why metals get more hot in the sun than other materials?
Yep Lightarrow, nice pointer that one. Sometimes one forgets As for why we see certain colors and not others? That's a really interesting question to me.
It seems as some prehistoric fishes saw colors too?There are some fish that is supposedly very ancient still living in Australia that have a similar set of cones and rods as we humans?And then you have animals able to see in the infrared spectrum, snakes f.ex.Take a look at ...sorry, you cannot view external links. To see them, please

Anyone know why metals get more hot in the sun than other materials?Have you tried to put under the sun a perfectly smooth silver surface and a black powder? Which gets more hot?Instead, if you mean to make an experiment with different materials but which have the same surface absorbance and specific heat, then you have to invoke thermal conductivity: a metal is usually much more conductive than other materials, so it propagates heat inside the material more than an insulator, becoming more hot.
It is obvious that metal is a good conductor of heat and UV rays from sun carry heat which strike in surface of metal cause heat to flow.
