What we conventionally call the "density" is more precisely known as the "mass density". Density can be expressed in any combination of mass and volume units; the most commonly seen units are grams per mL (g mL –1, g cm –3 ), or kilograms per liter.

WebWhen water freezes, its molecules lose energy and get stuck in a lattice structure in which they are farther apart from each other than in their liquid state, thus making ice less dense than water. The water molecules' low energy in their solid state prevents them from fulfilling the attraction of the hydrogen bonds and moving close to each other. http://galileo.phys.virginia.edu/classes/304/h2o.pdf
WebThis is because when water goes lower than 4 degrees celsius it expands. Meaning the molecules are further apart.
