Scientists think that if we heat a certain body to an infinite temperature, the wavelength is zero !! that is there is no light at all, in other words there is black radiation and the resulting fire resulting from burning this body of the infinite temperature is dark black.
When you light the charcoal, what is burning is the pure carbon. It combines with oxygen to produce carbon dioxide, and what is left at the end of the fire is the ash -- the minerals. Coke from coal is the same thing.Coke is coal that has been heated in the absence of oxygen to drive off the organics.f the temperature gets high enough, these compounds burst into flame. Once they start burning, there is no smoke because the hydrocarbons are turned into carbon dioxide and water (both invisible) when they burn. This explains why you see no smoke from a charcoal fire (or a fire that has burned down to embers).
