Question

Quizplus · Accepted Answer

The surface area of the liquid is not a factor that affects the boiling point of a pure substance. The boiling point is dependent on the vapor pressure of the liquid, which is related to the strength of intermolecular forces, and the enthalpy of vaporization, which is the energy required to overcome these forces and change the liquid into a gas. Surface area does not have a direct impact on either of these factors.
