Q2) Draw and explain the separation of liquids by using a separating funnel.

Q3) Define
Winnowing
Threshing
Distillation
Sedimentation​

Answer 1

Answer:

Q1) It is defined as the separation process in which solids are separated from the liquid. ... Sedimentation is a process by which heavier impurities present in liquid normally water settle down at the bottom of the container containing the mixture.

Sedimentation occurs when the suspended particles are large enough to settle to the bottom of a vessel under their own weight. ... Filtration works on the difference in particle sizes between the small liquid or gas molecules and larger solid particles.

Q2) A separatory funnel, also known as a separation funnel, separating funnel, or colloquially sep funnel, is a piece of laboratory glassware used in liquid-liquid extractions to separate (partition) the components of a mixture into two immiscible solvent phases of different densities.

Q3) Threshing is the beating of the crop against a stone to separate the grains from the stalk. Winnowing is process of separation of the husk from the seeds by blowing air. The lighter husk flies away and the heavier seeds fall down.

Solution: Winnowing: The process of separating heavier and lighter components of a mixture by wind or by blowing air is called winnowing. This method is used by farmers to separate lighter husk particles from heavier seeds of grain.
