Hi
I've read sufficient literature on Ice/Water expansion to understand that when water freezes into a lattice, the hydrogen bonds between molecules are longer than they are in liquid water, hence ice expands. However, everything I've read seems to skip over the reason why with statements like "because the hydrogen bonds are shorter in water the molecules can pack closer together".
It seems doubtful that the length of a hydrogen bond is related to temperature; super cooled water is still denser than ice, and I think I've read that water is at it's densest at 4 degrees centigrade.
Does anyone have an explanation / link to an article that explains why the hydrogen bonds in water are shorter than in the lattice of ice?
