Can you provide an example of an ordinal scale?
The Mohs mineral hardness scale is an ordinal scale.
What is the unit of measure of a scale?
The answer depends on what aspect of the scale you wish to measure: its hardness, reflectivity, mass, density, surface area, thickness, etc.
How hard are diamonds compared to emeralds?
Emeralds are compound of Boron, Aluminum and silicate. They are far less tougher than diamonds. Measured on mosh scale of hardness for minerals emeralds value is less than 8.0. On the same scale hardness of diamonds is 10.00
What is the mohs range of numbers?
The Mohs Scale of Hardness measures how well a substance resists scratching by another material.
What is the Hardness of pyrite on mohs hardness scale?
The hardness of the mineral pyrite, or Fool's Gold, is about 6 on the Mohs hardness scale. That's a little harder than a steel knife blade, but not as hard as the mineral quartz
Is gold harder than pyrite?
No, gold is not harder than pyrite. Pyrite has a hardness of 6-6.5 on the Mohs scale, while gold has a hardness of 2.5-3. This means that pyrite is harder than gold.
Which mineral will scratch glass hardness equals 5.5 but not pyrite?
Apatite is a mineral that has a hardness of 5 on the Mohs scale and can scratch glass. It is harder than pyrite, which has a hardness of 6 to 6.5 on the Mohs scale.
What do mineralogists do to identify minerals?
Hardness, luster, and scratch color help narrow down the possibilities . . . specific gravity and chemical analyses follow. As an example, gold and pyrite look about the same - both have a somewhat shiny luster. The streak color, though is black for pyrite and yellowish for gold. Hardness of pyrite is 6-something on the hardness scale, and gold is around 2.5, which is much softer.
A mineral with a hardness of 6?
A mineral with a hardness of 6 on the Mohs scale is feldspar. Feldspar is a common mineral found in many types of rocks, including granite. It is used in the production of ceramics and glass.
What is the gypsums hardness?
on number scale 2
What physical differences between pyrite and chalcopyrite?
Pyrite is typically a brassy yellow color and has a metallic luster, while chalcopyrite is a copper-yellow color and tarnishes to an iridescent blue or purple color. Additionally, pyrite has a hardness of 6-6.5 on the Mohs scale, whereas chalcopyrite has a hardness of 3.5-4.
What scale is used to rank the hardness or softness of minerals?
The Mohs Scale of Hardness determines the hardness of minerals by scratching them with commonly found objects. The minerals are assigned a number which corresponds to their hardness; higher numbers indicate higher hardness.
What is the scale for the Mohs hardness scale?
Granite is not assigned a number on the Mohs scale of hardness. The Mohs scale is a measurement of the relative hardness of minerals. Because granite is a rock composed of a variety of minerals, only the individual minerals which compose it have a Mohs hardness.
What do the numbers represent on mohs hardness scale?
The numbers on the Mohs hardness scale represent the relative hardness of minerals. The scale ranges from 1 (softest) to 10 (hardest), with each number corresponding to a different mineral's ability to scratch or be scratched by another mineral.
What is the scale used to measure the hardness of a mineral?
The scale used to measure the hardness of a mineral is called the Mohs scale. It ranges from 1 (softest) to 10 (hardest), with each number representing a different level of hardness.
What is the hardness of a ruby on the Moh's hardness scale?
A ruby is a mineral corundum. The Mohs hardness scale lists the following from softer to harder: Talc - 1 Gypsum - 2 Calcite - 3 Fluorite - 4 Apatite - 5 Feldspar - 6 Quartz - 7 Topaz - 8 Corundum (which includes the ruby) - 9 Diamond - 10 Ruby has a Mohs hardness of 9.
