Comment on Is ice heavier than water?

  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?

      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.

        It’s an old riddle that only works with imperial units. In traditional British fashion, the imperial weights and measures had two pounds in it, and you had to choose the right pound for the right thing you were weighing. The troy pound was used to measure metals and only has 12 ounces, whereas the pound used to measure feathers had 16, so a pound of feathers was 4 ounces heavier than a pound of lead or gold or whatever.

      Which would you prefer dropped on your head?

      Clearly the steel weighs more.

  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.

  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.
