What is MOHRS hardness?
Mohr's scale of hardness is used for minerals found in the earth. It basically refers to the ability of a harder material to scratch a softer material.The Mohr's Scale of hardness defines ten standard minerals on a hardness scale with hardness from 1 to 10, 1 being the softest and 10 being the hardest.The minerals are mentioned below.1. Talc2. Gypsum3. Calcite4. fluorite5. apatite6. Feldspar7. Quartz8. Topaz9. Corrundum10. Diamond'It is used in the following manner,A particular mineral is taken and scratched on the ten minerals mentioned above starting either from the 1 or 10 and based on its ability to produce a scratch on the softer material, its hardness is calculated.
How can minerals be identifed by their physical properties?
Yes
How could you find out whether copper is harder or softer that the plastic used in a plastic cup?
One way to compare the hardness of two materials is to see which of the materials can scratch the other.
Why cant you rely on any single test or property when you are trying to identify a mineral?
Different minerals can share many, but not all, mineral characteristics. Characteristics would include hardness, streak color, crystal shape, reactions to acids, flame tests, density, and others.
What materials are found in the earth's crust?
The earth's crust is made up of several elements: Silica, Calcium, Oxygen, Iron, Sodium, Aluminium, Manganese and so on. These elements combine in some form or other to make salts like Silicon-oxide, Calcium carbonate, Iron-oxide for example which are known as minerals and several minerals combine to make rocks. The distribution of rocks and minerals across the different parts of the globe is different, and hence geologist study different rocks/lithologies across the globe. And also this distribution will changes with depth. The upper crust has different elemental composition with respect to the lower crust. For example, the upper crust has more of aluminum with respect to lower crust whereas the lower crust ahs more Magnesium with respect to upper crust.
How is the value of a crystaline rock determined?
By levels of hardness, wear, scarcity, clarity and color, and association with other minerals. Also the habit of the mineral.
How do minerals break other minerals?
minerals don't break other minerals yet they can scratch other minerals based on their hardness which is measured by the Mohs scale
Why was Fredrich Mohs important?
He originally came up with the scale when classifying a private collection. He classified them by their physical characteristics rather than their chemical composition, using their relative hardness.
What is the difference between a minerals hardness and streak?
A minerals hardness is the ability to scratch or be scratched by other minerals and streak is the colored powder of a mineral that comes off when being scratched.
Which characteristic is used to identify minerals?
You can test its hardness on other minerals to find it hardness. It can help classify it better.
What properties distinguishes minerals from other substances?
Minerals crystal habit, cleavage, hardness, color and luster are the properties that distinguish minerals from other substances.
What is salts hardness?
The Mohs hardness of sodium chloride is 2,5. The Mohs hardness is established by comparison with other minerals, having a known hardness.
Resistance of a mineral to abrasion is known as?
The resistance of a mineral to being scratched is known as its 'hardness'. This is a relative measurement determined by whether it scratches, or is scratched by, other materials of determined hardness. Hardness is measured on the Mohs scale. To give to some idea, diamond (the hardest known mineral) is a 10, while talc (the softest) is 1. A copper coin is around 3, a fingernail is around 2, an iron nail is around 5. Quartz, for example, is a 7.
Can minerals and common objects with the same hardness scratch each other?
No, minerals and common objects with the same hardness are not able to scratch each other and leave a mark behind. For example, minerals with a hardness of 2.5 - 3 include gold and silver. Try scratching two pieces of jewellery made of gold and silver. It does not make a mark at all!
How hardness defined when identifying minerals?
Hardness is the ability of a mineral to resist being scratched. A diamond is the hardest mineral--which means that no other mineral can scratch it.
When is hardness defined when identifying minerals?
Hardness is the ability of a mineral to resist being scratched. A diamond is the hardest mineral--which means that no other mineral can scratch it.
How hardness of water can be remove?
Hardness of water can be removed with a water softener. These devices pump the water through salt to remove minerals and other particles.
