At vaporâliquid equilibrium, a liquid with individual components in certain concentrations will have an equilibrium vapor in which the concentrations or partial pressures of the vapor components have certain values depending on all of the liquid component concentrations and the temperature.
In measuring vapor pressure vs. temperature you will take advantage of the definition of boiling. Recall that boiling is defined as the temperature of liquid at which the vapor pressure is equal to. the atmospheric pressure. You will reduce the pressure above a liquid using the vacuum system. in the hood.
