So is boiling forced evaporation?
Vaporization occurs at any liquid-gaseous interface -- even at equilibrium,
whereat a characteristic vapor pressure exists because of confinement.
Boiling occurs throughout a liquid when conditions of temperature and
pressure allow vapor bubbles that form at container nucleation sites to
persist all the way to the upper surface. The onset of boiling is
characteristically noisy as the incipient vapor bubbles form but quickly
collapse against the container surface being heated because of the pressure
of the liquid surrounding them.
