What is the density of a penny 1982?

The density of a penny from 1982 is approximately 7.0 grams per cubic centimeter.


What is the density of a penny?

Density is 7.18 g/ml for post 1982 which is quite close to that of Zinc density of 7.14 g/ml. This makes some sense since the coin is 97.5 % Zinc and 2.5 % copper with a density of 8.92g/ml. The mass is: 3.11 grams [pre 1982] 2.50 grams [post 1982] The findings of a physics class: I calculated it in my physics lab with a group of students - To attempt to approximate for the different amount of nickel found in a penny past 1998, we took the avg of ten coins for thickness and mass. The density was found to be equal to 6.60 grams/centimeters cubic (approximately).


Which is more dense a penny from before 1972 or a penny from after 1972?

1972 has no significance in terms of changes in penny densities. The US Mint did not change the composition of its penny between 1909 to 1982, so any pennies from within this time period would have the same density. Pennies from this time period all contained the same proportions of metals (95% copper, 5% zinc.) Coins from post-switch 1982 to present day are minted of 97.5% zinc and 2.5% copper. Copper's density is ~8.9g/cm3 while zinc's density is ~7.1g/cm3. Considering the relative compositions of each version of the penny, the post-1982 penny would be the less dense penny, and the pre-1982 penny would be the more dense of the two.


What is a post 1982 penny made of?

A post-1982 penny is made of 97.5% zinc and 2.5% copper. The composition changed from primarily copper to primarily zinc in order to reduce production costs.


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 percent copper is a 1984 penny?

Next to none. Post-1982 pennies are only plated with copper, they are mostly zinc. The amount of copper on a post-1982 penny is miniscule and costs more to remove than melt value is.


What is the density of 10 pennies?

To find density you must first determine the mass and volume. Also, it matters if your penny or penny's are pre 1982 or post due to the metal they were created in. 10 post '82 penny's will weigh in approx. 25.0 grams. To get your volume = 3.14 X radius squared x height. In this case it would look like V = 3.14 x 9.5mm x 9.5mm x 1.27mm. Whereas V= 360 cubic millmeters. To get your density, we use Density = Mass/Volume. So Density=25\360, which equals .0694 g/cubic millimeters.

What is the density of a pre 1983 penny?

The density of a pre-1983 penny is around 7.1 g/cm³. These pennies were made of 95% copper and 5% zinc, giving them a higher density compared to post-1983 pennies, which are mostly made of zinc.

When was the penny post invented?

the penny post was invented in 1888


Which is more dense a pre 1982 penny or a post?

8.869 grams per cubic centimeter approximately. Some 1982 pennies are made of bronze alloy (pre1982) and some are copper plated zinc (post 1982). The change was made at the beginning of 1982 after some pennies had already been struck.
