Since water is a polar molecule and this means that there is a lot of forces of attraction.
Also because the hydrogen bonds in the water molecule require a lot of energy to break, hence the water have a high boiling point, melting point, and heat of vaporization too.
it has such a high boiling point because the electronic bond is so strong on it, the temperature has to get hotter to break the bond. the high the electionic strength the higher the temp has to be to break it
Water is a polar molecule.
It is made of two Hydrogen atoms and an Oxygen atoms. Oxygen is a more electronegative atom, (i.e. It has a stronger attraction for electrons) thus it tends to pull electrons away from the hydrogens. This means the electrons spend more time around the Oxygen atom, giving it a slight negative charge, while the Hydrogens are left with a slight positive charge. Because unlike electrical charges attract, one molecule of water is attracted to another (i.e. The positive hydrogen of one H2O molecule is attracted to the negative oxygen atom of another H2O molecule) forming a hydrogen bond. Because of this bond it takes more heat energy to overcome these bonds and turn the liquid of H2O into a gas.
The electronic bond is strong on a high boiling point causing the water to have a high boiling point. The temperature has to get warmer to break the bond. The higher the electronic strength, the higher the temperature has to break the bond.
It is mainly due to the intermolecular forces between molecules which is hydrogen bonding in the case of water. H-bonding is the strongest intermolecular force possible, and so it takes more energy (heat) to break those bonds.
Because the bond between the O atom and H atom is very polar and the shape of the molecule is in a bent configuration (think a Mickey Mouse hat from Disney World) this places the center of the partial positive charge between the two H atoms and the corresponding partial negative charge on the O atom itself. Since these charges are not in the same place, water is said to be a polar substance. This means that the partial negative charge on the O will attract the partial positive charge from the H's from a different molecule of water. This attraction most be overcome in order to turn the liquid into a gas. This attraction is known as hydrogen bonding.
Water has a boiling point, because, that is the temperature where it gets so hot, it turns to gas. Water can either be a liquid, gas or a solid. People want to known the temperatures so they can know how hot, or cold, it needs to be to turn into something else. Cooks certainly want to know water's boiling point, when making something with boiling water, such as tea or coffee.
Water has a high boiling point because of hydrogen bonding. There is a partial positive charge on the hydrogens and a partial negative charge on the oxygens. This means that the partial positive hydrogens are attracted to the negative oxygens on neighboring water molecules. This makes them "stick" together, thus raising the boiling point.
it mean a scale of hot water boiling
The process is just called boiling. At the boiling point, the water molecules spread out to form steam. Water vapour can form at any temperature, and that process is evaporation.
The attraction forces or the attraction between the bonds is relatively high as opposed to H2O or water which the bonds aren't as strong giving it a relatively low boiling point (: I feel like that helped :D
The boiling point of freshwater is lower than the boiling point of saltwater.
Vaporization, which can either be by evaporation or boiling.
Because of strong hydrogen bonding.

- Evaporation is possible at any temperature - At the boiling point vaporization occur
Water as steam racing towards the surface
vaporization
Vaporization (by boiling)
The vaporization that takes place below the surface of liquid is called boiling. The other one that takes place at the surface of a liquid is called evaporation
Below boiling point of water, water gets changed from liquid form into vapour form. This is called as vaporization. Thus change of state is possible even below boiling point. An liquid can be changed into solid at its freezing point. This is also a change of state.
vaporization
It is an event called vaporization.
Because it is closer to its enthalpy of vaporization (ΔvH), at boiling point the liquid molecules have highest kinetic energy so they easily escape from liquid as vapours.
