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.
Yes, ice contains hydrogen bonds. In ice, water molecules are arranged in a specific crystalline structure that allows hydrogen bonding to occur between the oxygen atom of one water molecule and the hydrogen atom of another water molecule. These hydrogen bonds are responsible for the unique properties of ice, such as its lower density compared to liquid water.
In most substances, as you solidify the product by cooling, its density rises (that is - it gets heavier). Water has a density inversion point, so ice is actually lighter than water - this is due to the way the molecules rearrange within the ice relative to the way they are packed together in the water. Hydrogen bonding in water molecules is quite strong (in the liquid phase) so the water is sort of "compacted" by this force - pulled together more tightly.
Cohesion is not directly attributable to hydrogen bonding between water molecules. Cohesion is the property of water molecules being attracted to each other due to hydrogen bonding, but it does not solely depend on hydrogen bonding for its existence.
The bonding in H2O is covalent bonding between the oxygen and hydrogen atoms. The oxygen atom shares its electrons with the hydrogen atoms to form a stable molecule. Additionally, H2O exhibits hydrogen bonding between molecules due to the partial positive and negative charges on the hydrogen and oxygen atoms, respectively.
The strongest intermolecular force between two molecules of water in ice is hydrogen bonding.

Density of water in solid state i.e. ice increases from 0oC to 4oC, where it has maximum density.Ice has a cage-liked structure with lots of vacant spaces in between because of extensive hydrogen bonding between the water molecules. When the temperature increases, this structure collapses as the hydrogen bonding starts to break and as such the water molecules occupy the void spaces thereby increasing the density.Beyond 4oC, the ice melts completely.

Hydrogen bonding is responsible for the cohesion of water molecules in both liquid and solid states. In ice, water molecules form a hexagonal lattice structure due to hydrogen bonding, which creates a stable and organized arrangement of molecules, resulting in the solid state.

Water has an unusual property that it expands as it freezes. This is due to the crystalline formation in conjunction with its hydrogen bonding. Since it expands, volume is larger. Density = mass / volume. Dividing by a larger number gives a smaller answer for the density. Water is most dense at 4 degrees Celsius.
In liquid water, the molecules are able to move more freely and can shift position, disrupting the formation of stable hydrogen bonds. In contrast, in ice, the water molecules are more rigidly held in a lattice structure, allowing for more stable and organized hydrogen bonding. This leads to the higher stability of hydrogen bonds in ice compared to liquid water.
As temperature increases, the density of air decreases because the air molecules move further apart. In contrast, as water temperature increases, its density decreases until it reaches its maximum density at around 4 degrees Celsius, after which it decreases. This unique behavior of water is due to its hydrogen bonding and is the reason why ice floats on water.

"Density" water is heaver than ice so the ice floats on it.Added:There is a Calvin and Hobbes cartoon in which Calvin poses the question to Dad:"Why does ice float?"Dad responds:"Because it's cold. Ice wants to get warm, so it goes to the top of liquids in order to be nearer to the Sun."See the related question below for an in-depth explanation.
