The '''boiling point''' is the [[temperature]] at which a specific substance [[boiling|boils]] under a certain [[pressure]]. Boiling occurs when the substance's [[vapor pressure]] is equal to the [[atmospheric pressure]]. At [[sea level]], the [[atmospheric pressure]] on [[Earth]] equals 1.00 [[atm]] (760 mm Hg).
