This chemistry video tutorial provides a basic introduction into vapor pressure. Vapor pressure is the partial pressure at which a substance's rate of evaporation is equal to the rate of condensation. This tutorial explains how to calculate the vapor pressure and normal boiling point of a substance using the clausius clapeyron equation. The normal boiling point is the temperature at which the vapor pressure of the liquid is equal to the atmospheric pressure at sea level. Vapor pressure increases with temperature. The boiling point of a substance is inversely related with elevation. Substances with high intermolecular forces tend to have a high boiling point and a low vapor pressure. Intermolecular forces included in this tutorial are london dispersion forces and hydrogen bonds - a special kind of dipole dipole interaction.
