Do Crushed Aluminum Cans Weigh More?
Crushed aluminum cans do not weigh more than their original form.
When aluminum cans are crushed, they become denser because the air inside the can is compressed. However, the density of the aluminum itself remains the same.
Density is a measure of how tightly packed the molecules of a substance are. The more tightly packed the molecules, the denser the substance. The density of aluminum is about 2.7 grams per cubic centimeter (g/cm³). This means that one cubic centimeter of aluminum weighs about 2.7 grams.
When an aluminum can is crushed, the volume of the can decreases, but the mass of the aluminum remains the same. This means that the density of the aluminum increases. However, the overall weight of the can does not change.
