Distillation is carried out by using this apparatus? one world answer
Answers
Answer:
Distillation, process involving the conversion of a liquid into vapour that is subsequently condensed back to liquid form. It is exemplified at its simplest when steam from a kettle becomes deposited as drops of distilled water on a cold surface. Distillation is used to separate liquids from nonvolatile solids, as in the separation of alcoholic liquors from fermented materials, or in the separation of two or more liquids having different boiling points, as in the separation of gasoline, kerosene, and lubricating oil from crude oil. Other industrial applications include the processing of such chemical products as formaldehyde and phenol and the desalination of seawater. The distillation process appears to have been utilized by the earliest experimentalists. Aristotle (384–322 BCE) mentioned that pure water is made by the evaporation of seawater. Pliny the Elder (23–79 CE) described a primitive method of condensation in which the oil obtained by heating rosin is collected on wool placed in the upper part of an apparatus known as a still.
HERE IS UR ANSWER
Distillation is carried out by using apparatus called still
The distillation apparatus, commonly called a 'still', consists of a vessel for plant material and water, a condenser to cool and condense the vapour produced and a method of collection, or 'receiver'. Material from the appropriate part of the plant for extraction is immersed in water in the distillation vessel.
