When water is a liquid, the molecules mix around very closely to one another. Each molecule is attracted to other by forces called hydrogen bonds. These bonds keep the molecules close together but not permanently fixed in one place.

Water ( , HOH) is the most abundant molecule on Earth's surface, constituting about 75% of the planet's surface. In nature it exists in liquid, solid, and gaseous states. It is in dynamic equilibr...

Question: Why does water expand when it freezes? bonnie j light Answer 1: Good question! Water expands when it freezes because of "hydrogen bonding." This means that the hydrogen on an H2O has a strong attraction for the "lone-pair", unbonded electrons on other nearby H2O molecules.

Unlike other liquids, water expands as it freezes to become ice; so ice floats on water because ice has less density than water. This is very unusual - just about every other liquid gets more dense as it cools;

Re: What makes water expand when it freezes? Area: Chemistry ; Posted By: William Stewart, Secondary School Teacher Science, Garrett Academy of Technology; Date: Thu Feb 20 21:00:40 1997 ... Water is they same way, which is why it expands, about 10% on average (which, incidentally, is why we see the top tenth of an iceberg).

Water expands when it freezes because the water molecules crystallize in such a way that the distance between molecules in the crystal is greater than the average distance between water molecules in their liquid state.
