$\huge \purple {AnsWer}$

1. Centrifugation- Centrifugation is the technique which involves the application of centrifugal force to separate particles from a solution according to their size, shape, density, viscosity of the medium and rotor speed. 
2. Threshing - The process of beating out the grains from the harvested crop plant is called threshing. Threshing is done to take out the grain from its outer covering called chaff. ... The cattle's feet crush the harvested crop plant due to which the chaff breaks up and the grain comes out..
3. Sedimentation and Decantation- In the sedimentation process, heavier components of the mixture settle on the bottom, due to gravity. Decantation follows sedimentation. The decantation process involves pouring clear, upper liquid out of the container, without disturbing the sediment..
4. Distillation- Distillation is the process of separating the components or substances from a liquid mixture by using selective boiling and condensation. Distillation may result in essentially complete separation, or it may be a partial separation that increases the concentration of selected components in the mixture. .
5. Condensation- Condensation is the change of the physical state of matter from the gas phase into the liquid phase, and is the reverse of vaporization. The word most often refers to the water cycle.
6. Sublimation - Sublimation is the transition of a substance directly from the solid to the gas state, without passing through the liquid state. ... The reverse process of sublimation is deposition or desublimation, in which a substance passes directly from a gas to a solid phase..
7. Saturated Solution- The term saturated solution is used in chemistry to define a solution in which no more solute can be dissolved in the solvent. It is understood that saturation of the solution has been achieved when any additional substance that is added results in a solid precipitate or is let off as a gas..
