What mineral scratches fluorite but cannot be scratched by glass?
The mineral that scratches fluorite but cannot be scratched by glass is apatite. Apatite has a hardness of 5 on the Mohs scale, while fluorite has a hardness of 4, allowing apatite to scratch fluorite. Glass typically has a hardness of about 5.5, meaning it can scratch apatite, but apatite cannot be scratched by glass.
Describe how to find the hardness of unknown mineral?
Minerals are tested for hardness by performing a scratch test. The unknown mineral is scratched with another object that the hardness is known. For example, a unknown mineral may be scratched with a piece of metal to compare the resistance.
A mineral can be scratched by a brass washer but cannot be scratched by a copper coin.is a test of what?
This scenario tests the hardness of the mineral using the Mohs scale of hardness. Since the mineral can be scratched by a brass washer but not by a copper coin, it indicates that the mineral has a hardness greater than that of copper (which has a Mohs hardness of 3) but less than that of brass, which typically has a hardness around 3 to 4. This allows for an assessment of the mineral's relative hardness compared to common materials.
What mineral can be scratched with a knife blade or a window glass?
Mineral that can be scratched with a knife blade or a window glass is gypsum.

What does the property of mineral hardness measure?
Mineral hardness measures the resistance of a mineral to scratching or abrasion. It is determined by the ability of a mineral to scratch another mineral or be scratched by it, as defined by the Mohs scale of hardness.
What mineral scratches fluorite but cannot be scratched by glass?
The mineral that scratches fluorite but cannot be scratched by glass is apatite. Apatite has a hardness of 5 on the Mohs scale, while fluorite has a hardness of 4, allowing apatite to scratch fluorite. Glass typically has a hardness of about 5.5, meaning it can scratch apatite, but apatite cannot be scratched by glass.
