They don't float, per se. Iron filings are not buoyant. However, they are small and light enough not to break the surface tension of the water and so they just lie on top.
If you pushed them to the bottom of the water, they will stay there.
Actually from what I have seen Iron filings sink and float ( half and half)

∙ 8y agoThe iron is actually burning, reacting with oxygen to produce iron oxide. The sparking is not observed with large pieces of iron because the smaller surface area results in a much slower rate of reaction.

Is unheated sulfur and iron filings is substance or mixture?
Sulfur and iron filings together are a mixture.
What liquid can be used to separate mixture of iron filings and sulfur?
Carbon disulfide can be used to separate a mixture of iron filings and sulfur. This is because carbon disulfide can be used to dissolve sulfur, thus leaving you with the iron filings.
Is iron filings an element?
Iron filings may or may not be pure. The ones used in experiments with magnets may not be pure iron. Most iron filings may have a few impurities. But iron (Fe) filings that are reagent grade will be very pure iron metal.
What is the densities of iron filings table salt pepper in water salt and iron filings and sugar in water?
angela and ev jackson are cool
How would you separate copper strands and iron filings?
I would separate copper strands and iron filings by using a magnet. The iron is magnetic, but the copper is not, so the magnet picks up the iron, but leaves the copper behind.
Why are iron filings used to find the magnetic field when copper filings are not?
Copper filings are not attracted to a magnet, as iron filings are.
What is the colour of iron filings?
mostly black, with some grey or silvery spots.
Are iron filings a mixture?
Iron filings may be pure elemental iron, it depends on the source of the iron.
Are iron filings a compound mixture or element?
pure substance
What is the separation method for iron filings and sulphur to obtain iron filings?
magnetic separation.
What are the properties of iron filings?
iron
Is unheated sulfur and iron filings is substance or mixture?
Sulfur and iron filings together are a mixture.
What forms of iron would rust the fastest thin iron plate iron nail solid iron cube fine iron filings?
Fine iron filings
How do you separate iron filings from iron carbonate?
Pure iron filings will be attracted to a magnet; but pieces of iron carbonate will not.
What technique will use to separate ashes and iron filings with water?
separate iron filings AND ash from water by filtration or evaporation then, if required, separate iron filings from ash by using a magnetic field,
Explain how you can use physical properties to separate filings from sawdust?
If they are iron filings, you can use the property of magnetism to remove the iron filings using a magnet. You will need to rinse the iron filings with water after you remove them with the magnet in order to completely remove the sawdust from them.
Can salt and iron filings be separated by physical means?
A magnet should be very good at picking out the iron filings.
