Match the separation techniques with the correct descriptions.
1. Heating a solid until it passes directly from the solid phase into the gaseous phase.
2. Separating a liquid from an insoluble solid sediment by carefully pouring the liquid from the solid without disturbing the solid.
3. The process of vapor returning to the solid phase without a liquid phase in between.
4. Heating a mixture to vaporize a volatile liquid component to make the remaining component dry.
5. Separating a solid from a liquid using a porous material, such as paper, charcoal, or sand, as a filter.
6. Using a solvent to selectively dissolve one or more components from a solid mixture.
A. Sublimation
B. Solids that Sublime
C. Extraction
D. Decantation
E. Evaporation
F. Filtration

Sublimation is the process where by a sample is heated to pass through solid phase to gaseous phase without the intermittent liquid phase. Example of substance that sublime is camphor.

2 = D

Decantantion

5 = F

Filtration is the process a liquid from solid using a porous material. This technique requires a set up and a good porous material eg filter paper.

6 = B

This technique is to separate a mixture of solids by converting them from solid phase to gaseous phase since they sublime.

3 = deposition.

The answer isn't in the option but deposition is the process of substance in gaseous phase to change into solid state without passing through liquid phase. Deposition is the opposite of sublimation.

4 = E
