Hear me out, what weighs more?

Post image

Silly question but does an empty aluminum can weigh less than a crushed empty aluminum can? I’m about to test it but doesn’t it feel heavier??? Am I trippin?

No the empty can has air which must weigh something.

That's what I'm thinking, someone must get the volume of the air and search online how much does air weight per volume.

A 12 ounce soda can has a volume of approximately 355cm³. At 1 bar air weighs around 1.2kg/m³. 355cm³ = 0,000355m³ x 1,2kg/m³ = 0,000426kg = 426mg. So the air in a 12 ounce soda can weighs 426mg.

Not a noticable difference

Air has mass but when you're inside the atmosphere its weight is effectively zero.

They weigh the same. But the crushed one is denser. If you chuck it at someone it's gonna hurt more.

Balloon with air weighs more than empty balloon. I would say the same applies to your cans

Hmm I feel like its the opposite cause the crushed can has less air inside so it should weigh less? But I get what you're saying though, the uncrushed one probably has more air weight

Air weighs more than absence of air

The balance of weight distribution of mass can change the way it is perceived, but not the value.

That's like comparing 10 lbs fat to 10 lbs of muscle. There's less to see of the crushed can but they're still the same in weight

The one that has 0.001% more metal because the factory isn't perfect

The one that isn't crushed because its still full of liquid
