Colour and heat!
Hello, I am having a physics investigation about thermophysics stuff. I investigate how the rate of temperature increase inside a box alters by the colour of the box.. There are a few questions i want to ask:
-a) Black box will abviously gets the hottest. But among red, blue, yellow, purple and green boxes, what order will it be?
I was thinking that if heat transfer into a box is related to wavelength or frequency, red may get the hottest (as it has the shortest frequency) or..blue may get the hottest (due to the longest frequency) Or, heat transfer may not be related to wavelength or frequency. I am very not sure..
b) How does the hot air get into the box? By molecules of the box material? Convection?
c) If the distance between the heat source and the box increases, what kind of relationship will there be? and why does the box that is the furthest from the heater gets the least heat?
Thank you soooo much for reading this and i hope you can write me back about them soon...
