Vapour Pressure| Boiling| Atmospheric P

[Epsillon]

Ok I do not get WHY an object boils when atmospheric pressure is equal to Vapour pressure.

Can anyone explain this? In my textbook it doesent explain it at all.

What is definition of boiling?

 

[Epsillon]

When atmospheric pressure= vapour pressure. and particles that are not neccessarly on surface are forming bubles and vaporizing

That's the most important part of it - boiling is vaporization that takes place not only on the surface, but also inside of the solution. That can take place ONLY when the vapor pressure is identical with or larger than the pressure of the surroundings. To some extent vapor pressure = atmospheric pressure is only a conclusion, not part of the definition.
