Their atomic latticework.
The hardness of lead is about 2.5 on moh's hardness scale. hope this helped wanka
hardness of peridot 7.0 mohs.
We use Mohs scale of mineral hardness to access the hardness of minerals, which calcite is one example.
u can chek the hardness by pH scale...lolz
The main idea web for hardness includes rebound, scratch, and indentation.
what is the difference between Shore-A Hardness & Barcol Hardness
Calcium
Both are two different scales of hardness measurement.
Rocks have different hardness because of variations in their mineral composition and the way those minerals are bonded together. Hardness is typically measured using the Mohs scale, which ranks minerals from 1 (softest) to 10 (hardest) based on their ability to scratch or be scratched by another mineral. Rocks with higher mineral densities or stronger atomic bonds tend to be harder.
It's actually a rather difficult question to answer as iron can be forged in a number of different ways, each giving a different hardness. I've attached a link to a site giving different hardness values for some treatments of grey iron.
Carbonate hardness is the measure of hard ions associated with carbonate and bicarbonate anions contained in the water.Noncarbonate hardness is the portion of total hardness in water that is not produced by carbonates, but primarily by sulfate anions.
micro is on a small scale and macro on a larger scale
There are many different levels of hardness in drivers seats. The level of hardness depends on the car and maker.
Chert has a hardness of 7 on the Mohs scale, making it relatively hard and durable. It is often used as a raw material for making tools and artifacts due to its hardness and resistance to abrasion.
The difference between strength and hardness is that the strength refers to the force that is present between the bonds. Strength attributes to how strong or weak the force between the bonds. Hardness refers to the nature of the force, which basically is how rigid or flexible the bonds between particles.
