What is it called when you perform a scratch test on a mineral?
It is called a streak and its purpose is to find the hardness of the mineral.
What is the difference between streak and hardness?
A minerals hardness is its relative ability to scratch or be scratched by other minerals. Diamond, for instance, can scratch all other minerals because of its hardness. Streak is the color of the mineral when powdered. This is usually accomplished by the streak test (swiping the mineral across an unglazed porcelain surface) which reveals a mineral's streak color, which may differ from the color of the specimen being tested.
What property might you test by rubbing one mineral directly against another mineral?
hardness
How is the hardness range for a mineral determined?
The answer is quite complicated in fact I don't know the exact answer. What I really know is that a geologist will probably know the exact answer. Geologists study rocks and rocks have lots of minerals. You can search the answer as well by looking at geologist websites. If it doesn't work then I hope someone else can edit this answer.
What mineral property if you testing if you scratch a mineral on ceramic tile?
You're testing it's hardness.
How is mineral hardness tested?
Mineral hardness is tested on a glass plate or usually a finger nail.
What mineral is used to perform a scratch test?
Bold
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.
What is the difference between a scratch test and a streak test?
a streak test is a test wheree you rub a mineral across a streak plate to see the color of its streak, which is a better indentifying factor of the mineral than the external color. A scratch test is when you scratch a mineral to find out its hardness on the Mohs Scale of Hardness. This is also another useful identifying factor
What is the purpose of a scratch test?
The scratch test is used for identifying minerals.You simply get a hard, white surface, and scratch the mineral on it.
What is used to test the hardness of a a mineral?
The Moh's scale is used to test the hardness of a mineral. It will be tested by a fingernail scratching it.
What is it called when you perform a scratch test on a mineral?
It is called a streak and its purpose is to find the hardness of the mineral.
What PROPERTY are geologists testing when they do a SCRATCH test?
Hardness
What is a way to identify minerals?
The scratch test, use a series of mineral with known hardness and scratch the mineral. From softest to hardest, and note where a scratch is made. You can also look for distinctive physical characteristics.
How do you estimate the hardness of a mineral that i'snt on the mohs scale?
By undergoing scratch test.
What kind of test is it when you scratch a mineral with a nail?
Most likely you would be testing to see if the mineral was harder or softer than the nail.
What is a mineral scratch test?
In 1822 scientist Friedrich Mohs developed a scale to measure the hardness of minerals. A mineral will scratch other minerals softer than itself and will be scratched by minerals that are harder.
