How does vapor pressure affect the design of vacuum distillation apparatus?

The temperature at which the vapour pressure at the surface of a liquid becomes equal to the pressure exerted by the surroundings is called the boiling point of ... Liquid ring vacuum pumps are dependant on the vapor pressure of the service liquid. The vapor pressure is linked to: ▫ The temperature of the service liquid. May 29, 2023 ... The normal boiling point of a substance is the temperature at which the substance changes from its liquid state to its gas state under a ... Some molecules of a liquid can escape from the liquid surface (evaporate) because of their kinetic energy. If these molecules, now in the vapour phase, are ...
