The elements inside the hot iron are energetic and some of that energy is released to its environment. The energy is released as photons at a certain frequency for each temperature of the hot iron. Energy at the frequency you are talking about is interpreted by the mind as the color red.
If the hot iron were even hotter it might look like a more pale red. At a higher temperature yet it might look quite white.

It's around the temperature of the hottest planet.
In the range of 200 to 300 degree centigrade
Because of the fire
When carbon monoxide is passed over red hot iron at 120°C, a reaction occurs to form a compound called iron carbonyl. This process is known as the Mond process and is used for the purification of nickel. Iron carbonyl is a volatile compound that can be easily separated, leaving behind purified nickel.
No, it is a chemical change Iron turns green means it is oxidized to ferrous (Fe+2) state.
Well, Ussually iorns can get pretty hot, But you don't see every day hot things get red do you . Well use fire for an example what colors are fire, What colors do you see in fire usually red orange yello wand blue and a fire is over 200 degrease so a red hot iron would be over 400 degrease. Nver ever touch a red hot iron ever unlease well that's somthing else. to britten up your day here is a joke Does the deer have a little doe? ya two bucks cracks me up!
Its its liquid state the iron is "molten" As it cools It looses heat and solidifies.
Hydrogen gas is produced.
That is called an ANVIL and most blacksmiths would have had at least 3 of them.
It symbolizes the apple that she eats.
the molten iron cool to form a solid
