Vapor pressure: is the pressure that the molecules at the surface of liquid exert against the external pressure, which is usually the atmospheric pressure.cold water is placed inside the condenser until the vapor converted in to a liquid, where it must be cold so that condensation occurs and also the process of entering and leaving water continues so that The water inside the condenser doesn't hear up and thus the Condensation process continues inside the condenser

The condenser is installed diagonally in the device in order to facilitate the flow of liquid from the condenser and also so that the direction of the cold water is opposite to the direction of the vapor, which increases the speed of condensation process and increase its effectiveness.There is a great similarity between Fractional Distillation and Simple Distillation (RBF, receiving head, hearing mantle, boiling chips, thermometer adaptor, condenser, Thermometer, ware in and water out) and there are one main difference which is fractional column.Boiling point: is the temperature at which the Vapor pressure equals the applied pressure.

Vapor pressure: is the pressure that the molecules at the surface of liquid exert against the external pressure, which is usually the atmospheric pressure. The Vapor pressure in every sensitive function of temperature. Boiling point: is the temperature at which the Vapor pressure equals the applied pressure.

Normal Boiling point: is the temperature at which the Vapor pressure of a liquid equal atmospheric pressure.

There is a great similarity between Fractional Distillation and Simple Distillation (RBF, receiving head, hearing mantle, boiling chips, thermometer adaptor, condenser, Thermometer, ware in and water out) and there are one main difference which is fractional column.

The recovery in fractional in larger than the simple and this is evidence, the fractional distillation is more effective than the simple distillation because in the fractional there are many Condensation / evaporation system (theoretical plats) but in the simple there are one evaporation / condensation system (one theoretical plats), and also the heating Was Slow until Here is a difference in temperature between the bottom of the device and the top, which head to increases the efficiency of the separation process.

Because the mixture is miscible the vapor pressure of the two liquids affected (decrease).So they evaporated at lower temperature.

The amount of liquid sample inside the RBF is not allowed to be less than half so that the RBF does not become a cooling be surface and condenser the Vapor and also not allowed to be more than 3\4 RBF so that there is no escape of the liquid inside the condenser (simple distillation). cold water is placed inside the condenser until the vapor converted in to a liquid, where it must be cold so that condensation occurs and also the process of entering and leaving water continues so that The water inside the condenser doesn't hear up and thus the Condensation process continues inside the condenser

The condenser is installed diagonally in the device in order to facilitate the flow of liquid from the condenser and also so that the direction of the cold water is opposite to the direction of the vapor, which increases the speed of condensation process and increase its effectiveness.
