Obviously I know ice is just solid water but would ice be heavier than the same volume of water if you account for the expansion of water as it freezes?

I’m only curious because I know that as water freezes it traps air molecules inside its crystalline structure so I was wondering if it trapped enough to cause a distinguishable difference in weight between the two states.

      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”

      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.

      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.

      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.

        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.
