A test using a fingernail, penny, or nail typically refers to a hardness test, specifically the Mohs scale of mineral hardness. By scratching the surface of a material with these items, one can determine its hardness relative to other substances. For example, if a fingernail can scratch a mineral but a penny cannot, the mineral's hardness is between 2.5 and 3 on the Mohs scale. This simple method helps in identifying minerals based on their resistance to scratching.

What is a mineral determined by using a fingernail penny or nail?
A mineral's hardness can be determined using a fingernail, penny, or nail by testing its ability to scratch or be scratched by these objects. The Mohs scale of hardness ranks minerals from 1 (talc) to 10 (diamond), with a fingernail typically rated at 2.5, a penny at about 3.5, and a nail around 5.5. By attempting to scratch the mineral with these items, you can estimate its hardness based on which objects can scratch it and which cannot.
A mineral determined by using fingernailpenny or nail?
A mineral can be tested for hardness using a fingernail, penny, or nail, which are common items that serve as reference points on the Mohs scale of mineral hardness. For instance, a fingernail has a hardness of about 2.5, while a copper penny is around 3.5. If a mineral can be scratched by a fingernail, it is softer than 2.5; if it can be scratched by a penny but not a fingernail, it falls between 2.5 and 3.5. This simple test helps in identifying the mineral's hardness and assists in classification.

How do you determine the hardness of a mineral?
The hardness of a mineral is determined by scratching it with materials of known hardness, such as a fingernail, a copper penny, a steel nail, or a piece of glass. The mineral is assigned a hardness value based on which material can scratch it. This is known as the Mohs scale of hardness.

What is a test for minerals that is determined by using a fingernail penny or nail?
The Mohs Scale of Hardness was developed by German mineralogist Friedrich Mohs. Higher numbers are assigned to minerals that scratch the harder common objects on the scale. i. 10- Diamond ii. 9- Corundum iii. 8- Topaz iv. 7- Quartz v. 6.5- Streak Plate vi. 6- Orthoclase Feldspar vii. 5.5- Glass, Masonry Nail, Knife Blade viii. 5- Apatite ix. 4.5- Wire (iron) nail x. 4- Flourite xi. 3.5- Brass (wood screw, washer) xii. 3- Calcite, Copper coin (penny) xiii. 2.5- Fingernail xiv. 2- Gypsum xv. 1- TalcMoh's hardness test
