How mineralogist identify and classify materials?
there are a few basic tests to identify a material. hardness, color, lustor, crystal form, cleavage, and streak. I believe this is all of them, but it has been several years. They are classified by the same tests that identify them. For example, diamond is classified as a 10 hardness material (the only 10 hardness material) Glass is 7 hardness.
Why hardness is important in metallurgy?
For steels especially, there is a high correlation between hardness and strength. Hardness is also indicative of wear resistance for a material.
Is hardness extensive or intensive?
No matter what size a sample is, if is hard, it will still be just as hard. This means that hardness is an intensive properties. Intensive properties do not matter what size of sample is being used. Extensive properties will change if sample size is changed.
Does density of Thorium mean the same as the hardness?
The density of thorium is 11,724 g/cm3. The Mohs hardness of thorium is 3. Density is the ratio between mass and volume. Hardness is a measure of resistance of a material under a compressive force.
How is the hardness of a diamond related to the way it was formed?
Diamonds are formed into crystals with a perfect octahedral crystal habit. Hardness is associated "...with the crystal growth form, which is single-stage..." "The Mohs scale of mineral hardness characterizes the scratch resistance of various minerals through the ability of a harder material to scratch a softer material." All quotes according to Wikipedia research.
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.
What is hardness of Mechanical Engineering Materials?
The hardness of any material is how much it keep it's original shape when put under pressure against another material. Example a drill or cutting tip will have to harder than the material it has to cut, so must maintain it's cutting edge and shape to cut effectively. Hardness is usually measured using a vickers scale, or the old Brinell way which are both a method of testing the hardness of a material.
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?
Hardness: the measure of the resistance of a solid to being scratched or dented ?
What does hardness in metal mean?
the hardnessb of a material
What sample of hardness material?
magnets steal
Is hardness a property used to distinguish a substance?
Yes, hardness is a specific property of each material.
