Because in water hydrogen bonding is not permanent due to random motion where as in ice it is permanent also in ice k.e.is also lower
Of course. The reason for water's solid structure when frozen is due only to hydrogen bonds, which form a type of crystal lattice structure. When heat is applied, these bonds break, and water becomes liquid once again. then you crap yourself.
Water molecules are linked by hydrogen bonds.
Within a water molecule is covalent bonds. between water molecules are hydrogen bonds.
Hydrogen bonds cause water to expand when it freezes. As water cools and freezes, the hydrogen bonds between water molecules form a crystalline structure with a more open arrangement than in its liquid state, causing it to expand and become less dense.
Van der Waal forces determine the attractiveness of molecules to others outside of covalent and ionic bonds. For water, the dipole interaction between the slightly + hydrogen end of the molecules are attracted to the slightly - oxygen end.
The hydrogen bonds in liquid water are less stable than in ice because the molecules in liquid water are moving around and constantly breaking and reforming bonds, whereas in ice, the molecules are more rigidly arranged in a crystalline structure, allowing for stronger and more stable hydrogen bonds to form.
Water is less dense as a solid than as a liquid. This unusual property of water is due to hydrogen bonds. As water freezes, each molecule forms stable hydrogen bonds with its neighbors, holding them at "arm's length" and creating a three dimensional crystal. In Ice Hydrogen bonds are stable In liquid water hydrogen bonds constantly break and reform.
Water requires a lot of energy to change its phase because of its strong hydrogen bonds. When heating water, energy is needed to break these bonds so that the water molecules can move more freely from a solid to a liquid or a liquid to a gas. Similarly, when cooling water, energy is released as the water molecules form more stable hydrogen bonds in the solid or liquid state.

Water molecules are linked by hydrogen bonds.
When water freezes, there is an increase in hydrogen bonds. As the temperature decreases, water molecules come closer together, forming a crystalline structure in which hydrogen bonds become more stable and stronger, leading to the solidification of water into ice.
Hydrogen bonds between water molecules are primarily responsible for holding them together in the liquid state. These bonds are formed between the slightly positive hydrogen atom of one water molecule and the slightly negative oxygen atom of another water molecule.
Melting. During melting, the hydrogen bonds between water molecules are broken thus causing the state to change from the solid to the liquid state where there are LESS (and not no) hydrogen bonds.
Hydrogen bonds in ice create a stable and open lattice structure, causing water molecules to arrange in a hexagonal pattern. This results in ice being less dense than liquid water, allowing it to float. The hydrogen bonds also give ice its crystalline structure and contribute to its high melting point.
When water is heated to boiling, hydrogen bonds between water molecules are broken. These hydrogen bonds are responsible for the structure and properties of water and hold water molecules together in a liquid state. As the temperature increases, the kinetic energy of water molecules overcomes the hydrogen bonds, causing them to break and water to evaporate into steam.
Hydrogen.
Water molecules H2O consist of two hydrogens each joined to a central oxygen attom by covalent bonds. Water molecules stick to one another by hydrogen bonds, but these are not permanent bonds in the liquid.
