The boiling point occurs when…Group of answer choicesThe vapor pressure is equal to the external pressureThe vapor pressure is lower than atmospheric pressureThe intermolecular forces are strongThe temperature of the liquid exceeds the external temperature

The normal boiling point of a liquid isQuestion 6Select one:the temperature at which the gas molecules have more kinetic energy than the molecules in the liquid.the temperature above which the substance cannot exist as a liquid regardless of the pressure.the temperature at which the liquid will usually boil.the temperature at which the vapour pressure equals 101.3 kPathe only temperature at which there can be equilibrium between liquid and gas.

The boiling point of a compound is the temperature at which a liquid is converted to the phase.
