What is the harness of a mineral if it scratches a penny but will not scratch glass?
Google "Mohs hardness scale". This is a relative hardness scale which compares one mineral's hardness to another. (It is between 3.5 and 5.5 on the Mohs hardness scale)
What mineral can scratch glass but can be scratched by steel file?
The mineral that can scratch glass but can be scratched by a steel file is quartz. Quartz has a hardness of 7 on the Mohs scale, allowing it to scratch glass, which typically has a hardness of around 5.5. However, a steel file, which has a hardness of about 6.5 to 7, can scratch quartz.
What mineral is harder than calcite but wont scratch glass?
Fluorite is a mineral that is harder than calcite but won't scratch glass. Calcite has a hardness of 3 on the Mohs scale, while fluorite has a hardness of 4. However, glass typically has a hardness of about 5.5, making it too hard for fluorite to scratch.
If a mineral is a 6 on the mohs scale what can it be scracted by?
A mineral with a hardness of 6 on the Mohs scale can be scratched by anything harder than a 6, such as minerals with a hardness of 7 or higher. It will not be scratched by minerals with a hardness of 5 or lower.
What mineral will scratch glass but not a sreak plate?
A mineral that can scratch glass but not a streak plate is quartz. Quartz has a hardness of 7 on the Mohs scale, which allows it to scratch glass (which has a hardness of about 5.5) but is harder than the streak plate, typically made from porcelain, which has a hardness of around 6-7. Therefore, while quartz can leave scratches on glass, it will not produce a streak on a streak plate.
What is the hardness of an unknown mineral that scratches glass but will not scratch quartz?
The unknown mineral would have a hardness greater than 5.5 (the hardness of glass) but less than 7 (the hardness of quartz). Based on the Mohs Hardness Scale, the unknown mineral would likely have a hardness between 6 and 7.
What is the hardness of a mineral if it scratches a penny but will not scratch glass?
Between 3.5 and 5.5 on the Mohs scale of mineral hardness.
How is hardness tested?
Mineral hardness is tested on a glass plate or usually a finger nail.
What hardness does a mineral have if it does not scratch glass but scratches an iron nail?
The mineral would have a hardness between 5.5 and 6.5 on the Mohs scale. It cannot scratch glass (hardness of about 5.5) but can scratch an iron nail (hardness of about 4). This places it in the range of minerals like orthoclase feldspar or apatite.
What hardness does a mineral have if it scratched by glass but scratched an iron nail?
It would have to be 5.0 because glass has a hardness of 5.5 and an iron nail has the hardness of 4.5
How is mineral hardness tested?
Mineral hardness is tested on a glass plate or usually a finger nail.
What is the harness of a mineral if it scratches a penny but will not scratch glass?
Google "Mohs hardness scale". This is a relative hardness scale which compares one mineral's hardness to another. (It is between 3.5 and 5.5 on the Mohs hardness scale)
How do you determine the hardness of a mineral?
The hardness of a mineral is determined by scratching it with materials of known hardness, such as a fingernail, a copper penny, a steel nail, or a piece of glass. The mineral is assigned a hardness value based on which material can scratch it. This is known as the Mohs scale of hardness.
Which mineral will scratch glass but will be scratched by a nail?
This mineral is likely quartz. Glass has a hardness level of around 5.5, while quartz has a hardness of 7. A nail, which is made of iron, generally has a hardness around 4.
What hardness does a mineral have if it is scratched by glass but scratches an iron nail?
It would have to be 5.0 because glass has a hardness of 5.5 and an iron nail has the hardness of 4.5
Which mineral can be scratched by glass but not a penny?
The mineral that can be scratched by glass but not a penny is calcite. Calcite has a hardness of 3 on the Mohs scale, which is lower than the hardness of glass (5.5) but higher than that of a penny (2.5).
What does a mineral have if it is scratches by glass but scratches an iron nail?
It would have to be 5.0 because glass has a hardness of 5.5 and an iron nail has the hardness of 4.5
