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 difference between beta and alpha test Brief?
A brief explanation of the difference between beta and alpha test is that alpha test is usually in-house and is part of basic development. Beta test is right before product release and typically includes customer input.

What is difference between regression testing and retesting?
A regression test is a test where a previously known bug is tested for after a change. A retest is simply repeating a test.
Difference between quantitative and qualitative test?
Qualitative test represents the substance and a quantitative test shows the amount.First Deals with descriptions, second one with numbers
What materials do you need to test the streak?
To test the streak of a mineral, you will need a streak plate (unglazed porcelain), the mineral sample, and a way to scratch the mineral against the streak plate to observe the color of the powder residue left behind.
What kinds of tests can you do to figure out the difference between diamonds and calcite?
The tests you can do is the streak test, the luster test,the finger nail test(which is scratching it ti see if its hard or not).
How is the streak test different than the scratch test?
because the lava inside the magma moves more and more that it just exlodes
What isn't a streak test used to help identify every mineral?
A streak test is not used to identify minerals with a hardness greater than 7 on the Mohs scale, as these minerals can scratch the streak plate. Additionally, streak tests may not be effective for identifying minerals that have a streak color similar to the streak plate itself.
What does a mineral and streak tell you and how do you test for it?
The streak of a mineral can distinguish between two samples that have the same color. The streak is often a different color. To test streak, use a streak plate. This is a piece of unglazed porcelain, like the back side of a tile.

Does the streak test work with all minerals?
No it does not work with all minerals. For if you did not know streak plates have a hardness of 7 (maybe a little lower or higher) on the Mohs scale. Some minerals are harder than 7 though. If they are harder they will not work with the streak test. some examples are Diamond, topaz, and corundum.
What test would you perform to distinguish hematite form copper how would you carry out this test?
A few things used to identify minerals are streak tests, hardness, cleavage, solubility, magnetic.Streak test: When you scrape a mineral on a streak plate it leaves behind powder of a certain color. Hematite leaves a red streak. I don't know what streak copper has.Hardness test: minerals have different hardness, their ability to be scratched or scratch. this can be determined by seeing if you can scratch a mineral with your finger nail or if the mineral will scratch a piece of glass. I don't know if this test will do much good though in determining copper from hematite.Cleavage: Cleavage in mineralogy refers to when you break a mineral, how it fractures. Does it fracture into cubes, rhombus shapes, conchoidal, etc.Solubility: copper is soluble in acids and forms green-blueish solutions, hematite is insoluble.Magnetic: hematite is sometimes slightly or strongly magnetic. copper is not magneticAfter you test your samples, look up in a book or manual to see which mineral(s) have matching properties.

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.
Why could the streak of corundum be difficult to determine?
Corundum has a streak that is typically colorless, making it difficult to determine on a streak plate. The hardness of corundum (9 on the Mohs scale) can also affect the accuracy of the streak test, as it can scratch the streak plate instead of leaving a distinct streak.
