Boiling Point: Explanation and Study Guide

What is Boiling Point?

The boiling point of a substance is the temperature at which the vapor pressure of the liquid equals the pressure surrounding the liquid and the liquid changes into a vapor. At the boiling point, the vapor pressure of the liquid is equal to the atmospheric pressure.

Factors Affecting Boiling Point

The boiling point of a substance is affected by factors such as atmospheric pressure, intermolecular forces, and the molecular weight of the substance. Generally, as atmospheric pressure increases, the boiling point of a substance also increases.
