The bonds that hold water molecules far apart from each other are ice. The hydrogen bonds' postulation in ice keeps them far apart from one another.
liquid water
The bonds that hold water molecules far apart from each other are ice. The hydrogen bonds' postulation in ice keeps them far apart from one another.
Water molecules form hydrogen bonds to other water molecules.
Hydrogen bonds hold water molecules to each other. They're the strongest of the Van der Waal's forces.

hydrogen bond bonds water molecules with other water molecules.
The Molecules(Atoms) stretch their bonds so they spread further apart from each other.
Hydrogen bonds.
Water is composed of molecular bonds, but forms hydrogen bonds with other water molecules. Hydrogen bonds are not actual bonds, but they cause an attraction between the water molecules, which is why water is adhesive.
Water molecules form hydrogen bonds to other water molecules.
When water freezes, rigid hydrogen bonds between water molecules are formed. Each Oxygen atom in the ice lattice has 4 bonds. 2 covalently bonded hydrogen atoms, and 2 hydrogen bonds ('H-Bonds'). These hydrogen bonds are slightly longer than the covalent bonds, and hold the H2O molecules apart. When the ice melts, the rigid hydrogen bonds collapse and molecules move closer together. Normally when solids melt, the molecules move slightly further apart, and hence the liquid is less dense than the solid.

Water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
adhesion
Ice is less dense than water because as water cools and becomes a solid (freezes), hydrogen bonds form between the water molecules. In the liquid phase of water, the molecules "snuggle up" to each other in the fluid. But as water goes solid, the hydrogen bonds dictate that the molecules will have to "stop snuggling" and move apart a bit as those hydrogen bonds set up spacing in the now-solid molecules. Ice has become less dense than the water that it formed from because the hydrogen bonds, which begin forming at just above 0 °C, force the molecules apart a bit to form the solid (ice) matrix.
