Question

How do water’s relative densities as a solid and a liquid differ from that of most other substances

Answer 1

Solid water is less dense than liquid causing it to float while other substances are mainly more dense as solids.

Answer 2

Answer:

The relative densities of the water as liquid and solid vary from the corresponding densities of the other substances. The density of the water's solid form is less in comparison to the density of water in its liquid form. While the majority of the other substances upsurges in density when they get solidify. This is why the ice floats on the surface of water's liquid form.
