The video tutorial explains vapor pressure as the pressure exerted by evaporating liquid particles in a sealed container. It discusses the equilibrium between evaporation and condensation, where vapor pressure becomes constant. Factors affecting vapor pressure, such as temperature and intermolecular forces, are explored. The video also compares different liquids, highlighting how their escape kinetic energy and intermolecular forces influence vapor pressure.
