Can a diamond be scratched by an iron nail?
Diamond is the hardest known natural element/mineral. It cannot be marked. However, and conversely it can mark other objects.
Which metal conducts heat faster aluminum or iron?
aluminum
What is harder a diamond or iron?
Diamond by far, is harder than steel. Steel is an alloy of constituents being iron and carbon as the major ingredients. It is hard due to the interaction between iron and carbon molecules which causes them to stay binded together giving strength. Diamond, on the other hand, is solely made up of carbon (diamond is an allotrope of carbon). The attracting force and the perfect stable geometry gives carbon a lot of strength, making it the hardest natural substance ever known.
Why does an aluminum cube sink but a sheet of aluminum float?
Have you heard of Archimedes. Well he stated that the weight of water displaced by an object is equal to the weight of the object. From here we conclude that object being more denser than water sinks those being less dense than water floats. An Aluminum cube has a much higher density than that of water and the sheet is less dense than water. Thus the former floats while the latter sinks. Now you also might have noticed that an iron nail sinks while an iron ship floats. I hope now you can answer this question!!
What tool is most useful to determine whether an object is made of iron?
just about any tools that you want. Wrenches are made of iron except some specialized ones made of brass or bronze when there is a need for less friction, or some made of aluminum for light weight.
Why iron corrodes but aluminum does not?
Both iron and aluminum will oxidize. When iron oxidizes the product (rust) easily crumbles away, exposing more iron to oxidation. Aluminum is even more reactive than iron, but the aluminum oxide that forms is one of the hardest known substances and forms a protective layer that, even though it is microscopic, shields the aluminum from corrosion.
What are Hard metal?
Diamond is the Hardest in the world. Coming from carbon. Iron, Gold , Aluminium are hard metals
Is steel the hardest natural material?
No. I don,t know what is but diamond is one of the hardest. Besides, steel is an alloy of iron and carbon, not a naturally occurring material.

What is the hardest element in the world iron or diamonds?
neither its tungsten, a diamond is harder but it is not an element since it is not in the periodic table.
What are some hard metals?
Diamond is the Hardest in the world. Coming from carbon. Iron, Gold , Aluminium are hard metals
What are the pros and cons of iron vs aluminum cars?
IRON STRONGER.....ALUMINUM LIGHTER.....IRON IS HEAVY.....ALUMINUM WILL BREAK EASIER THAN IRON
Is aluminum foil iron?
Shut up....iron is an aluminum foil
Can iron be scratched with a iron nail?
They are of the same hardness, so I believe not. that depends how wet and thin the iron is. the nail's usually thin, unless it is a hardware nail. the best thing to cut a nail with is a diamond's (the hardest material) sharp edge.
What does recycling do to iron and aluminium?
Recycling iron and aluminum makes iron and aluminum or you're doing it wrong.
Is aluminum more durable then iron?
aluminum is more durable than iron.
What is the simplest gem in regard to its chemical composition?
Diamond is pure carbon Also, Sapphire is Aluminum Oxide. (Analogous to how Iron Oxide is rust!)
