What do geologists use to classify a mineral's hardness?
Geologists use the Mohs scale of mineral hardness to characterize the scratch resistance of various minerals through the ability of a harder material to scratch a softer material. In this scale diamond is the hardest material and talc the softest.
What material in bone is responsible for giving it hardness?
red bone marrow and calcium
If a material has a hardness of 8 can it not be scratched by a material with a hardness of 7?
False
What are the factors on which hardness of a material depends?
Hardness of a material depends on the type of bonding between atoms.
Why hardness is a intensive?
Because the hardness is not dependent to the size of a material sample.
What is the Brinell hardness test used for?
The Brinell hardness test is a standardized test in material science. It measures the hardness of a metal by measuring the indentation on the material caused by an indenter.
What is the meaning of 'hardness' in science?
hardness is that property of material by virtue of which, the material cfan resist abrasion, wear and tear, penetration etc.
What is the property of the material by which it offers resistance to scratching or indentation is?

Is hardness a property used to distinguish a substance?
Yes, hardness is a specific property of each material.
The hardness of bone is due to what?
The hardness of bone is due to the calcium salts deposited in it.The exceptional hardness of bone, which allows it to resist compression, is attributed to the presence of inorganic hydroxyapatites. Hydroxyapatites such as calcium phosphates are particularly important for bone hardness. Organic substances such as collagen fibers contribute to tensile strength, but not to hardness.the presence of inorganic hydroxyapatites.
