Density is mass by volume. The volume changes because of the crystalline lattice. The mass doesn’t change. I’m trying to decide if you’re trolling or not.
Comment on Is ice heavier than water?

The same volume of ice as water will be lighter, since it is less dense. That’s why ice floats on water

They aren’t wrong. You’re keeping the mass constant, they’re keeping the volume constant.
I think the confusion might come from their phrasing: “the same volume of ice as water,” which could mean “the same volume of ice as the volume of water” (which is what they meant), but could also be interpreted as “the same volume of ice in the form of water.” The latter interpretation doesn’t fit the rest of their sentence though, so we can safely assume they meant the former.

They talk about comparing the same volume of ice and liquid water, e.g. 1 cm³ ice vs. 1 cm³ liquid water, not two specimen of the same mass.

Would depend, are you saying the same volume in same state or different states? If you freeze 1 volume of liquid water and compare it to a liquid same volume of water I would question it. Is the trapped air in ice from the ambient environment or is it dissolved air expelled from the water as the molecules lock together?
Would be interesting to freeze two samples in sealed containers with one being in a vacume.

Well, that’s the answer in terms of comparative density, but in terms of comparative weight, I’m wondering if the ice would indeed be heavier since it commonly traps additional gases in the freezing process.
So yeah, I’m not entirely sure if OP was talking more about weight or density.

I blame the fact I just woke up for not thinking about the difference in density 😅 I was just filling up my water bottle with ice cubes and thought about how ice expands and my brain went “bigger must mean heavier”

So here’s a question for you? What weighs more, a kilogramme of steel or a kilogramme of feathers?
corvi@piefed.social 2 months ago
The feathers. You have to carry the weight of what you did to those birds.

And I need a container to carry that many feathers.
I can carry the kg of steel in one hand.

Which would you prefer dropped on your head?

Clearly the steel weighs more.
