So I had these auto tools in a car that is exposed to sunlight, hot day and such. The sun did not reach inside the car but I saw some strange effects on the tools. There were iron tools, chrome steel tools, red painted steel tools. By far the hottest of the bunch was the chrome steel star wrench (used to loosen tire bolts). The weird part is, that piece was mirror finish chrome, you can see yourself in the metal easily. So why is this part the hottest of the bunch, I mean not a little hotter but too hot to touch, maybe 70 degrees C, hot enough to burn my hand handling it, while the others were maybe 45 degrees, warm but not nearly so hot as the star wrench. What is going on here?
I would have assumed the chrome steel to be the coolest because of the highly reflective surface but even a rusty iron hammer was a lot cooler, with brown rust all over the metal surface, I would assume it to collect heat more efficiently than chrome steel.
Color me confused!
