Is dry ice a molecular crystal
WebAug 31, 2024 · When ice melts, some of the hydrogen bonds are broken and the rigid crystal lattice collapses somewhat. The hexagonal channels become partially filled, and the volume of a given amount of H 2 O decreases. This is the reason that ice is less dense than water and will float on it.
