hydrogen bonds
Frozen water molecules are larger and expand. In liquid form H2O is smaller
liquid water because as water freezes it creates crystallized forms of its molecules expanding the area it takes up, which is why ice floats because it is less dense then the liquid form
Water doesn't spontaneously freeze (thank goodness). It freezes because heat is being removed from it (by a fridge, for instance). As heat is gradually removed the molecules of water vibrate less and less as they lose energy. Eventually the random vibration almost stops and the molecules form into a fixed array like an army on parade. This lattice structure is so much stronger than individual water molecules flying about hither and thither and is called ice.
Under O oC water become ice (a solid).
Snowflakes are star-shaped due to the molecular structure of water and how it freezes. When water freezes, water molecules arrange themselves in a hexagonal lattice, forming a six-sided structure. As more water molecules freeze and accumulate, the lattice grows and gives snowflakes their characteristic star shape with six branches. The intricate patterns and variations in snowflake shapes occur due to the unique environmental conditions and the individual paths water molecules follow as they freeze in the atmosphere.

Ice is a material with crystalline structure.
When it freezes, water becomes ice.ICE- A surface, layer, or mass of frozen water.
Ice exist in a very great variety of crystals (hexagonal crystalline structure).
Almost no liquids do that. Almost all become more dense when they freeze. Water is a startling exception. Water is one of the only known substances whose solid form floats in its liquid form. When water freezes, it forms crystals which occupy more space than its molecules would if they were packed together. That's because of the special shape of the water molecule, and the hydrogen bonds that it forms with other water molecules. The shape tends to form an open crystalline structure as the temperature drops below 4 degrees Celsius. By the time it freezes, it's about 9% less dense than water.

Water freezes when there isn't enough heat available to separate hydrogen-hydrogen bonds between the molecules. When hydrogen bonds persist, the molecules form into a solid crystal lattice, which is ice. Although water may be cooled down to 32°F / 0° C, additional energy called the "heat of fusion" must be removed from the molecules for ice to form.
Water molecules are already in liquid form.
when it is in the form of ice. When water freezes it expands. If a rock has a crack in it and water goes in the crack and freezes, it will expand and melt over and over. eventually it can split the rock.
Fresh water will freeze first. This is because when water freezes the hydrogen bonds form a rigid structure (Ice). Salt and sugar molecules interfere with this formation.
