✔Hey Mate......✍

✔Question:☄

• State the principle underlying the following techniques. (i) Fractional Distillation (ii) Evaporation.☄

✔Answer:☃️

✍The basic principle used in Fractional distillation: ⚘

• The basic principle of this type of distillation is that different liquids boil and evaporate at different temperatures. ⚘

• So when the mixture is heated, the substance with lower boiling point starts to boil first and convert into vapour.⚘

✍The principle used in Evaporation:☃️

• Principle: Evaporation is a surface phenomenon. The water molecules at the surface of a container tend to come out.☃️

• So they gain heat energy fro. the nearby molecules and evaporates. ☃️

• As a result eveporation takes place.☃️
