Why doesnt the all the water instantly vaporize when you reach the boiling point?

The boiling point is the temperature where a substance BEGINS to vaporize. So all of the water doesn't necessarily need to boil off instantly. To vaporize, molecules of water need to have energy. Only at the boiling point do they have enough energy to boil away, and when they do, they carry this energy with them. This means that a constant supply of heat for a certain period of time is needed for all water in a sample to boil off.

Why does sugar raise boiling point?
Sugar increases the boiling waters temperature because it is an impurity. Impurities are dissolving molecules. Another example of an impurity is salt, although salt has a much greater affect on boiling water than sugar does. Impurities will increase water's boiling point because they are able to dilute the concentration/ solution of the water. In other words: the amount of water molecules will decrease and so will the amount of molecules that are able to vaporize at the specific temperature. This causes the need for a higher temperature in order to gain the same amount of vapor pressure, thus raising the boiling point.

What will be the state of melting point and boiling point of petrol?
Melting point it would liquefy, boiling point it would vaporize.
When heating a sample of pure water to the boiling point why doesn't all of the water instantly vaporize when you reach the boiling point?
as each molecule of water evaporates it takes heat with it, lowering the temperature of the surrounding water, so it takes time before every molecule evaporates.

What is a volitile liquid?
Violate liquids are liquids that will evaporate, or vaporize easily. They evaporate at room temperature. Violate liquids have a low boiling point.
In order to get liquid water to become water to become water vapor what must be energy?
Energy must be added to liquid water so that it reaches the boiling point, at which point the water will vaporize into water vapor.
