In our high school Chem 1 Class, we had this lab where we went around doing simple experiments and determining whether the change was a physical one or a chemical one. Well, when one of the stations had be perplexed. At this station we had a Nickel Chromium Wire with an Aluminum handle, and what we had to do was put the wire in the Bunsen burner. When I put the wire part into the yellow/orange part near the top of the burner, the wire, like expected, quickly glowed red/orange (Like burning embers). When I put it in the hottest part or the burner at the blue triangle flame, the wire did not glow. I asked my teacher and he said the wire should have glowed at any part of the flame, yet it did not. He tried the experiment and got the same result. So, why does the wire glow in the red/orange part of the flame, but not the hottest part?
