Why does metal glow red when you heat it with a blow torch? Do different metals glow other colors under heat?

Answer 1

The colour red has more to do with what temperature it is -- The heat is giving off a glow.

In fact the colour of suns tell scientist how hot they are. red is one of the cooler colours !

White is hotter and blue (I think) is the hottest.

I use the colour red of molten glass to gauge whether it is hot enough to start winding it on a mandrel to make a bead. That means the glass (soda glass) is somewhere around the 1500 range. That's very iffish- you would need a thermometer to know for sure.

Answer 2

something can exchange colour whilst it fairly is heated. as long because it does not use up or evaporate that is going to likely be a lifeless pink warm, a shiny pink warm, or white warm at diverse temperatures. it somewhat is easy to work out in steel by using fact it purely says there and can be observed unquestionably. you may desire to quite attempt that with stones and get equivalent effects. you're watching the radiation from a heated merchandise. It has no longer something to do with oxidation that would make oxides that practice diverse colours. it somewhat is the warmth itself.

Answer 3

The electrons gain energy and then fall back to lower levels thus radiating energy back.

Answer 4

This phenomenon is called "Blackbody radiation."
