Question

what does ice float in water

Answer 1

When water is cooled from room temperature it first contracts in volume and becomes increasingly dense as do other liquids, but at 4° C water reaches its maximum density. ... ice float on water because because it lighter than water and the molecules are in cage like structure which make it float on water.

Hope this helps you friend
Thanks ✌️ ✌️

Answer 2

The water, which is less dense than the rocks, will float. ... As water cools below 4 C, the hydrogen bonds adjust to hold the negatively charged oxygen atoms apart. This produces a crystal lattice, which iscommonly known as 'ice'. Ice floatsbecause it is about 9% less dense than liquid water.
