Freezing. In this type of phase transition, all known liquids, except helium, will turn into a solid when its temperature is lowered or below its freezing point. That is why water turns to solid ice when frozen which is due to water molecules losing energy and not vibrating or moving around as vigorously anymore which in turn allows more stable hydrogen-bonds to form between water molecules, as there is less energy to break the bonds. As freezing point is reached, crystal lattice structure is imposed on water molecules, causing density to decrease, thus water expands as it freezes, and ice floats atop water.
