Like other molecules, water molecules, H2O (or H-O-H), move, vibrate and rotate in many ways at a temperature above absolute 0. When water molecules are heated up, the total energy of the molecules is increased and result in moving, vibrational and rotational speeds increase. The structure of a water molecule provides a special attracting force between water molecules, hydrogen bond, to keep water molecules together. (Hydrogen bond: a hydrogen atom in a water molecule has an attraction to the oxygen atom in another molecule. It is an inter-molecular bond.))
Ice (<= 0 deg C):
In the solid form, the hydrogen bond is strong, because the molecules don't have much energy to move around. And, thus, a crystal structure is formed.
Melting (>= 0 C and <= 100 C):
At the melting point, the water molecules gain enough energy to break the hydrogen bounds. This allows the molecules to move around each other. But, still the molecules are bound together by the hydrogen bounds so that water molecules don't move around freely.
Boiling (>= 100 C):
When the energy of water molecules increases as being heated, the moving, rotational, vibrational speeds increase. To some point, the boiling temperature, the moving energy of water molecules is high enough to totally break the hydrogen bonds and escape away from other water molecules. The water molecules become free and in the form as vapor or steam, gaseous form.
Heat up more?
When a water molecule is heated up to a very high temperature, the energy of relative motion between H and O atoms exceeds the bond between the H and O, covalent bond and break the bond. As a result, 2 ionized hydrogen (2 x H+) and a ionized oxygen (O--) are formed. This normally happens at extremely high temperature or under high speed molecular impact.
Vaporization
When a water molecule, located near the surface of liquid water, gets hit by other particles, air or another molecule, it absorbs some or all the moving energy from the incoming particles and speed up motion for a short moment until the energy is passed along to other molecules around it or further out. In some cases, when everything is right, the water molecule may gain enough energy, move in the proper direction and escape the other water molecule. This energy increase is not introduced by temperature increase and can happen at any temperature.

What bonds are broken when water is heated to boiling?
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.
Water-water bonds are called?
hydrogen bond
When liquid water is heated most of the energy that the water initially absorbs is used to raise the temperature of the water or break hydrogen bonds?
Yes, when liquid water is heated, the majority of the energy goes into increasing the temperature of the water molecules. However, a portion of the energy is also used to break the hydrogen bonds holding the water molecules together before all of the water molecules can reach a higher energy state and transition into the gaseous phase.
Can water form hydrogen bonds form with itself?
Yes, water can form hydrogen bonds with itself. Each water molecule can form hydrogen bonds with up to four neighboring water molecules, resulting in a network of hydrogen-bonded water molecules, which gives water its unique properties like high surface tension and cohesion.
What type of bonds hold one molecule of water to another molecule of water?
A hydrogen bond is the attractive interaction of a hydrogen atom with an electronegative atom(<-wikipedia). Hence, in a water molecule the positive hydrogen atoms are attracted to the negative oxygen atoms. Just know that the hydrogen bond mentioned above is not a chemical bond. If it were, it wouldn't be water anymore. Another force between water molecules are London Dispersion Forces.
What is water when heated?
Water molecules are attracted to each other, resulting in the formation if weak chemical bonds, called hydrogen donds. When water is heated the heat energy disrupts the hydrogen bonds reulting in hydrogen bonds between water molecules to be broken.
What is heating water?

What bond is broken when starch is heated?
The hydrogen bonds in starch molecules are broken when starch is heated. This results in the gelatinization of starch, where the starch molecules absorb water, swell, and become thickened.

When water is heated most of the energy that water initially absorbs is used to?
It breaks the hydrogen bonds between the water molecules
What types of bonds will break when frozen water is heated and becomes liquid?
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.

On the basis of hydrogen bond explain the anomalous behaviour of water when it freezes?
Anomalous expansion of water takes place because when water is heated to 277K hydrogen bonds are formed. Though ice is supposed to expand when it is converted into water, this gradual formation of hydrogen bonds causes it to contract, i.e. the contraction caused due to the formation of hydrogen bonds is greater than the actual expansion of ice. At 277K water has the maximum density because all the hydrogen bonds are formed by 277K beyond which water obeys the kinetic theory of molecules, an increase in volume when heated and the reverse when cooled. The same thing happens in the reverse when water is cooled beyond 277K. I think this should be the answer of this question
How do bonds form between water molecules?
The bond between water molecules is known as a hydrogen bond.
What kind of bond does water commonly make?
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.
