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
