Is that really your question? Do you mean in the experiment when iron and sulfur are mixed and heated why does it glow red? During the experiment iron and sulfur begin to react at higher temperatures. As they react there is a release of energy, some of which is heat and some is in the red light region. During the reaction iron sulfide is produced.
More simplistically, heating many things caused them to glow red. Heating iron can cause the iron alone to start giving off a red glow because while absorbing the heat the electrons in the atoms move to a higher energy level. Some of that absorbeb energy is released as the electrons move back to lower energy levels releasing some energy as red light waves.
What else can I help you with?
If you continue heating a piece of room temperature metal in a dark room what will be its first visible color?
The first visible color of the room temperature metal will depend on the specific metal being heated. Typically, metals start to glow red when heated to a certain temperature. This red color is due to incandescence, where the metal is emitting thermal radiation as it heats up.
When metal is heated the light emitted is because it gains energy as they return to lower energy levels?
Yes, when metal is heated, the atoms in the metal absorb energy and become excited. As they return to their normal energy levels, they release this excess energy in the form of light, which is known as incandescence. This is why heated metal appears to glow.
What happens to a nichrome wire when someone turns on a switch?
It will get heated and start to glow.
When the metal ball is heated can it go through the metal ring?
when the ball is heated, it will pass through the unheated ring.
Does glass heated in a hot flame glow and becomes fluid?
Glass can soften and become pliable when heated in a hot flame, but it does not glow like metal does when it reaches high temperatures. It does not become fully fluid like a liquid, but it can become molten and flow like a thick syrup.
When metal heats up what will it do?
It will expand, and if heated enough, will start to glow and melt.
What metal gives off an orange glow?
Iron typically gives off an orange glow when heated. The color of the glow is due to the emission of light energy as the metal reaches high temperatures, which causes it to emit a characteristic colored light.
Does metal produce energy when heated?
If you heat metal sufficiently, it will glow, which is an emission of energy, however that energy comes from the heat energy you have added to the metal; the metal itself is not producing energy.

Will the volume of metal decrease if it is heated?
No, the volume of a metal increases as it is heated. It expands.
What happens to a nichrome wire when someone turns on a switch?
It will get heated and start to glow.
Why do train tracks expand?
Metal expands when it is heated. Since track is made of metal then it expands when it is heated by the sun.
Why a glass jar can be easily opened if the metal lid is heated?
because metal will expand when it has been heated up
When the metal ball is heated can it go through the metal ring?
when the ball is heated, it will pass through the unheated ring.
What is light produced by heating a piece of metal until it glows?
If you heat a metal it will begin to glow faintly red at around 500ºC, or about 950ºF. If you continue to heat it, by 800ºC (about 1450ºF) the glow will a dull cherry red and at about 1100ºC (about 2000ºF) the colour will be a lemon or light yellow colour. Finally, at temperatures above about 1300ºC (about 2400ºF) the glow appears white, and very bright. Precautions must be taken, as looking directly at an object at this temperature can damage your vision.
Why do metals glow when they are melted?
Metals glow when they are heated because.... to heat metals to glowing point you need heaps of energy, but instead of releasing this energy as just heat, a piece of metal will release it as light. This is kinda the same reason the sun glows, because it has so much energy it releases it as light.
