SUMMARY
The vapor pressure of a liquid is solely dependent on temperature and remains unaffected by atmospheric pressure. This principle is evident when considering a highly volatile liquid in a sealed container; increasing the pressure does not significantly hinder the evaporation rate. Instead, the rate of condensation is influenced by the partial pressure of the vapor molecules, establishing equilibrium based on partial pressure rather than total pressure. These facts highlight the distinct roles of vapor pressure and atmospheric pressure in phase transitions.
