like, why does the iron fillings and why doesnt the lump?
Is it just because the surface area is higher so there more reaction or something?
*so bad for this*
but thank you in advanceee..

A lump of iron can "burn" only at a very limited surface. You are correct that if the lump is reduced to a small pile of filings they will have a greatly increased surface area. This will permit heat and oxygen to react more energetically with the iron which will burn. In like manner, the pile of filings will rust faster in water than the lump of iron.

Iron doesnt burn. It glows due to the heat absorbed from the flames of the Bunsen burner.
Now, Iron filings are very small and and take large amounts of heat in a short duration of time. But Iron lump has a large surface area and takes a longer time to absorb heat.

Iron is Non-Organic COAL IS Organic
When Iron is heated to the vaporization level it goes through Red hot, White hot Liquid and then vapor. The changing colors cause it Flash.
Coal does not go through those stages, because is is flammable. Where Iron is not.
The state in which Iron is used on Earth is in the Frozen state. Just thought I would through that in to make your think about it.

I am no scientist but I think it is the ratio of oxygen to metal. Put a 9 volt battery to some 000 steel wool . A sure fire starter.
