Since filaments of iron wool are much thinner than an iron nail, they therefore have a much higher ratio of surface area to volume, and burning takes place at the surface, so the more surface, the more easily it burns.

Why does the rusty nail weigh more than the original nail?
rust is iron oxide. so what's happening at the atomic level is oxygen is bonding to the iron. The iron stays with oxygen attached, the oxygen is the increased weight.
Why iron nail sinks in water?
its density is greater than water, so it sinks.
Why does a rusty nail weigh more than the original nail?
Rust is iron oxide, a molecule consisting of iron and oxygen. The mass of the iron in the rust molecules comes from the original nail, but the mass of the oxygen has come from the air. When rust forms on iron, the mass of the iron object is increased by the mass of the oxygen that has combined with some of the iron.
Why does an iron nail has more force of attraction than a piece of chalk and rubber band?
Because they have different magnetic properties; iron is strongly ferromagnetic.
Does iron conduct electricity better than better than steel?
Iron conducts electricity better than steel. Steel is considered a very poor conductor compared to most metals since it has a very low electron mobility.
Is an iron nail heavier than a wooden stool?
The wooden stool is heavier than the iron nail
Is a iron nail a good heat conductor?
Yes. But, compared to what? Better than lead but not as good as silver.
Is the BaByliss 20-Piece Hot Roller Set better than an iron?
Yes, the Babyliss hot roller set is better for your hair,for the iron can burn or damage your hair.
Why do wood burn faster than iron?
because iron doesn't burn...it melts.
Can a nail float in water?
The nail sinks in water because the gravitational force attracts it downward toward the earth, there is an upthrust of water on the nail which pushes it upwards but, the downward force acting on the nail is greater that the upward force. Hence, the nail sinks in water. The density of the iron nail is more than that of the water, this means that the upthrust of water on the iron nail is less than the weight of the nail, so it sinks. The cork floats while nail sinks this happens because of the difference in their densities. The density of a substance is defined as the mass per unit volume. The density of the cork is less than the density of water. This mean the upthrust of the cork is greater than the weight of the cork. The density of the iron nail is more than that of the water, this means that the upthrust of water on the iron nail is less than the weight of the nail, so it sinks.
Which holds better a nail or screw why?
A screw holds better than a nail.
Why would the mass of a rusted nail would be greater than the mass of the nail before?
When iron rusts, it combines with oxygen to form iron oxide (rust). You now have the original mass of iron PLUS the mass of the combined oxygen.
An iron nail is more strongly attracted to the?
An iron nail is more strongly attracted to the magnet than to the wooden box the magnet is stored in.
Why is Batman better than iron man?
Because Iron Man is better than batman
Why a rusty nail weighs more than the original nail?

Why doesn't a nail in an electrical circuit rust?
The rusting of a nail (iron) is an oxidation process. An iron nail in an electric circuit has a much higher potential difference than its oxidation potential, so it cannot oxidize.
What happen when an iron nail is dipped in copper sulphate solution. why does the colour changes?
The iron is a more active metal than copper, so the iron atoms in the nail replace the copper atoms in the copper sulphate solution, so it becomes iron sulfate. The copper atoms will start to build on the iron nail, as well.
