"WebIce floats on water. In liquid H 2 O, molecules form a temporary H-bond with each other. It is due to the movement of molecules, bonds are broken and reformed. Therefore, there is less regularity and less free space. However, when the temperature of H 2 O is lowered below 4 0 C, its molecules become regular and form permanent H-bond. So empty ...
