Define:

(a) Filtration

(b) Sublimation

(c) Evaporation

(d) Sedimentation

(e) Decantation

(f) Distillation

(a) The process of separating insoluble solid particles from a liquid by allowing it to pass through a filter is called filtration.

(b) The process in which a solid changes directly into its vapour on heating without changing into its liquid state is called sublimation.

(c) Evaporation is the process of converting a liquid into its vapour state, either by exposing it to air or by heating.

(d) The settling down of suspended, insoluble, heavy solid particles in a solid-liquid mixture when left undisturbed is called sedimentation.

(e) The process of pouring out the clear liquid, without disturbing the sediment, is called decantation.

(f) Distillation is the method of getting a pure liquid from a solution by evaporating and then condensing the vapours.
