4. the fact that ice is less dense than water is related to the fact that (1 point)
the molecular structure of ice is much less orderly than that of water
the molecules of ice are held to each other by covalent bonding
ice has a molecular structure in which water molecules are arranged randomly
ice has a molecular structure that is an open framework held together by hydrogen bonds ***
