Is the mohs hardness scale is it relative to a scale?
Mohs scale is a relative scale that defines the hardness of a mineral as its ability to produce a scratch on the surface of a reference mineral. The number for hardness assigned to the tested mineral is the number given to the hardest material that the mineral can scratch. The reference materials are 1) Talc 2) Gypsum 3) Calcite 4) Fluorite 5) Apatite 6) Orthoclase 7) Quartz 8) Topaz 9) Korundum 10) Diamond These materials can be tested more quantitatively for their hardness by standardized tests on how resistent they are against scratching. The mohs scale is thus more of a handy tool when one is out in the countryside and wants to have a rapid test if one found a quartz or a calcite.
How does a scientist test a mineral hardness?
By hardening then cooling
What property of graphite allows it to be useful writing tool?
its low hardness score
A test for this mineral is you pour acid on it what mineral is this?
Pouring hydrochloric acid, or HCL, over a mineral will cause carbonate minerals to effervesce. This application is called the "acid test," it simply examines the mineral or rocks reaction to acid. Calcite is the most commonly found carbonate mineral and it will fizz during the acid test. Dolomite is another carbonate mineral; however, it will only fizz if it is first powdered. Experiments also show that undiluted vinegar can cause effervescing, but it produces less vivacious results. Some sedimentary rocks that fizz include chalk, coquina, oolic limestone, fossilferous limestone, and micrite. The metamorphic rock marble also fizzes.
Which tool is best for seeing the internal structure of a mineral?
Using a rock hammer to break the mineral apart I know this because I am a earth science teacher for 15years
What test is used to identify a minerals color?
A streak test is used to determine a minerals streak color. This can help in with the identification of minerals. A streak test is performed by rubbing the mineral on an unglazed ceraminc tile, then observing the color of the streak which is left behind. All minerals do not leave streaks. Harder minerals will not streak, but this can also be used as a tool for identifying the mineral, if you are familiar with the hardness scale.

How is the hardness of a material determined by a hardness testing machine?
The hardness of materials is a function of their elastic modulus. As such a number of tests are used to measure hardness. Relative hardness can be assessed by the scratch test where one material or mineral is used to scratch another. As such, the material that manages to scratch the other is harder, while the one that is scratched is softer. This comparative or relative hardness method is the basis of the Mohs hardness scale. More quantitative methods of assessing the hardness of materials are based on the height of rebound of a hammer of known mass allowed to fall from a fixed height (which imparts a known energy into the material), where the height to which it rebounds is dependant on the properties of the material. As such, the higher the rebound, the larger the elastic modulus of the material and the harder the material. Two examples of tests which use this methodology are the Schmidt hammer test and the Shore scleroscope test. Another common method used to measure the hardness of materials is to assess the depth of indentation of a tool of fixed dimensions at a specified applied load into the material of interest, where the larger the size of indentation, the softer the material. This methodology is commonly used for testing metals and forms the basis of the Vickers, Brinell and Rockwell hardness tests. Please see the related links for more information.
What is a tool that identifys the hardness ratings?
Durometer
What makes a diamond a cutting tool?
it's hardness
How do you tell an uncut diamond is real?
The field test for a diamond stone is its extremehardness. Lacking any tool to test extreme hardness, take the raw stone to a jeweler, who can use a probe to confirm that the stone is or is not a diamond.
What makes the hardness of a diamond useful?
Most diamonds are used in industry and not in jewelry. Their hardness makes diamond useful as a cutting tool.
How do you compare tool steel grades?
Tool steels are compared to each other. They are usually measured by toughness, hardness and wear resistance. The toughness is detemined by an Charpy impact test. The hardness is measured by a Rockwell hardness tester and reported as HRC or RC. The wear resistance is measured by a number of tests that measured the amount of material removed from the original size after a repetitive movement against an abrasive material. These figures are then gathered and presented on a chart. The grades are then compared with one another based on these three properties. See the links below for more information on comparing tool steels.
What property of graphite allows it to be useful writing tool?
its low hardness score
What mineral can be cut with a knife?
Several minerals are rated on the Mohs scale of hardness above glass. You can see from the scale, below, that window plate glass is rated at 5.5 on the 10-point scale. Commonly, industrial diamonds attached to a tool are used to score class where a cut is desired, then the worker taps the glass with a rubber mallet and the glass separates along the score.
