What is the density of a post 1982 penny?
The density of a post-1982 penny, which is made of 97.5% zinc and 2.5% copper, is around 6.99 g/cm^3.
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.
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 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).
