Why does ice float

A. ice is less dense than water
B. ice has a higher pH than water
C. ice has a lower pH than water
D. ice is denser than water​

Answer 1

Ice actually has a very different structure than liquid water, in that the molecules align themselves in a regular lattice rather than more randomly as in the liquid form. It happens that the lattice arrangement allows water molecules to be more spread out than in a liquid, and, thus, ice is less dense than water.

Answer 2
