What can a copper penny scratch?
A copper penny can scratch materials with a Mohs hardness of 2.5 or lower, such as gypsum, talc, and some plastics. It will not scratch harder materials like glass, steel, or most ceramics.
How does the mass of zinc penny compare to a copper penny?
Copper pennies (95% copper, 5% zinc) weigh 3.11 grams. Modern zinc pennies (97.5% zinc, 2.5% copper) weigh 2.5 grams.
Which is heaver a 2006 penny or a 1982 penny?
A 1982 penny is heavier than a 2006 penny. In 1982, the composition of the penny changed from being mostly copper to mostly zinc. The higher copper content in the 1982 penny makes it heavier than the 2006 penny, which is mostly zinc.
What is the weight of the zinc 1983 Penny and what is the weight of a copper 1983 penny?
The weight of a zinc 1983 penny is 2.5 grams, while the weight of a copper 1983 penny is 3.11 grams.
Is a coper penny a conductor or insulator?

The copper of the penny will rub off the file
What can a copper penny scratch?
A copper penny can scratch materials with a Mohs hardness of 2.5 or lower, such as gypsum, talc, and some plastics. It will not scratch harder materials like glass, steel, or most ceramics.
Can a penny scratch a igneous rocks?
Most igneous rocks are harder than a penny, so it is unlikely that a penny would be able to scratch an igneous rock. Igneous rocks are typically composed of minerals like quartz and feldspar, which have a higher hardness than copper (the main material in pennies).
Which mineral would a penny scratch?
A penny would scratch minerals with a lower hardness rating such as calcite, gypsum, or talc. Minerals like quartz or topaz would not be scratched by a penny because they are harder than the metal in a penny.
What mineral can be scratched by a steel knife but not a copper penny?
Copper. Copper has a hardness of 2.5-3 on the Mohs scale, while a steel knife generally has a hardness of around 5.5 - 6.5. This means that a steel knife can scratch copper, but a copper penny cannot scratch a steel knife.
Can quartz scratch corundum?
According to the Mohs scale of mineral hardness, quartz (7) will not scratch any mineral with a higher number on the scale. Corundum is listed at 9. Therefore quartz will not scratch corundum, but corundum can scratch quartz.
Will the mineral topaz scratch quartz or will quartz scratch topaz Why?
topaz has a hardness of 8 on the mohs hardness scale, quartz has a hardness of 7. topaz will be able to scratch quartz, but quartz can never scratch topaz.
Which material would scratch the other quartz or calcite?
Quartz, with a hardness of 7, will scratch calcite, with a hardness of 3.
Can quartz be scratched by a penny?
No. According to Mohs Hardness Scale, Quartz has a hardness of 7 while copper has a hardness of about 3. The higher number indicates a greater hardness.
What is a penny on Mohs hardness scale?
A penny has a Mohs hardness of around 3.5. This means that it can be scratched by harder materials like glass or quartz, but it can scratch softer materials such as chalk or talc.
