Key words :-
Centrifugation : The method to separate the fine particles which are suspended in a liquid by rotating the mixture at a high speed.
Evaporation : The process in which liquid changes into gaseous from on heating. This method is used to separate soluble solid substances from a liquid.
Hand picking : The process in which the substances can be separated by hand picking. The components of a solid solid mixture can be separated by hand picking.
Separating funnel : The process of separating two immiscible liquids with the help of a separating funnel is known as separating funnel.
Loading : Sedimentation is a slow process and the finer particles take time to settle down. In order to speed of this process, we take help of loading. The loading helps the fine suspended particles to settle down.
Magnetic separation : The method to separate components of magnetic and other substances with the help of a magnet.
Sublimation :The process in which a solid changes directly into its gaseous state is called sublimation.
Winnowing : The mixture is allowed to fall from a height. The light components gets separated from the heavier ones because of the air blow.
