Why hardness is a intensive?
Because the hardness is not dependent to the size of a material sample.
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.
How the hardness of diamond is measured?
The hardness of a diamond is measured using the Mohs scale of mineral hardness, which ranges from 1 (softest) to 10 (hardest). Diamond is the hardest naturally occurring substance and is rated at a 10 on the Mohs scale. To determine the hardness of a material, a sample of known hardness is used to scratch the surface of the material in question; if the material is scratched, it has a lower hardness rating than the sample.
If a material has a hardness of 8 can it not be scratched by a material with a hardness of 7?
Yes, a material with a hardness of 8 can scratch a material with a hardness of 7, but not the other way around. Hardness is a measure of a material's resistance to scratching, so a material with a higher hardness value can scratch a material with a lower hardness value.
How do you Calculate the hardness of a water sample?
u can chek the hardness by pH scale...lolz
Sample problem on speed and its solution?
hardness
What are the factors on which hardness of a material depends?
Hardness of a material depends on the type of bonding between atoms.
How to identify a hardness of a unidentified material?
To identify the hardness of an unidentified material, you can use a hardness test such as the Mohs scale, Vickers hardness test, or Rockwell hardness test. These tests involve applying a specific amount of force to the material's surface and measuring the indentation or scratch it creates to determine its hardness.
What is hacksaw hardness testing?
Hacksaw hardness testing is a simple and rudimentary method used to estimate the hardness of a material. It involves cutting a groove into the material with a hacksaw blade and then comparing the resistance encountered while cutting to a known material hardness scale. This method is not as precise as standard hardness testing methods but can provide a rough estimate of the material's hardness.
How was friederish mohs and what did he develop?
In 1812, German mineralogist Friedrich Mohs developed a hardness scale for minerals (now universally used on metals, etc.)The scale was based on whether the sample could be scratched by a material of known hardness. The standard was Diamond, with a Mohs Hardness Number of 10.
Which physical property is shown by scratching one material with another?
The physical property shown by scratching one material with another is hardness. Hardness is a measure of how resistant a material is to scratching or indentation.
Hardness of a material that scratches the knife blade?
The hardness of a material that scratches a knife blade would typically be higher than the hardness of the knife blade itself. This implies that the material is able to physically deform or remove material from the knife blade due to its greater hardness. This property is commonly assessed using the Mohs scale of mineral hardness.
