Lost me there, remember, didn't do Physics :P If you have the time and don't
mind, could you explain that to me?

Yes, molecules in direct contact with the AIR become gaseous, but that is
only the top layer, they are being bounced off by "air" molecules (I know
air isn't one gas) if I remember correctly?
To boil something, molecules within the solution will become gaseous instead
of just molecules that can be "bounced" off.
Please, no-one be afraid to shout me down here, I'm no chemist/physicist!
(Although I doubt that will be much of a problem...)
