| − | '''Boiling''' is the transition of matter from [[liquid]] to [[gas]]. A liquid boils when its [[vapor pressure]] is equal to the pressure on the liquid (usually [[atmospheric pressure]]). Boiling results in bubbles forming at [[nucleation sites]] and rising to the surface of the liquid. Eventually, the liquid will completely transition to the vapor phase. | + | '''Boiling''' is the transition of matter from [[liquid]] to [[gas]].
