galvanized wire in the oxygen in the fierce out, Mars, and the sodium block, magnesium in the oxygen out, not the phenomenon of mars.
Q: Why did the galvanized wire go out in the oxygen, and the spark of Mars?
[answer]: galvanized wire in the oxygen in the fierce out, Mars, and the sodium block, magnesium in the oxygen out, not the phenomenon of mars.
This phenomenon is determined by the composition of the galvanized wire. Pig iron or steel wire is used in the experiment of galvanized wire, iron and steel is iron and carbon alloy (containing iron and carbon are two elements of complex substances). When the carbon in the galvanized wire will produce carbon dioxide, solid into gas, the volume will shrink rapidly.
Galvanized wire can be viewed as iron coated with carbon, extinguished, the surface compared to shallow carbon can contact with oxygen, produce carbon dioxide gas, wrapped around the iron (this is the molten state) radiation in.
The more carbon containing zinc, the more obvious the phenomenon of the sparks of mars. Be like the iron coated carbon bag wrapped in explosives like dynamite, to turn the iron fried away.
Sodium and magnesium containing less combustible impurities, the extinction is just a light.
