(1) are separated without any chemical reactions. There are many
different kinds of mixtures. Different mixtures are separated in (2) ways.
Physical (3) separates the components of varying sizes using a
spoon or any scooping material or by picking. The use of (4) can be done
to separate the metallic materials from nonmetallic materials. (5) is the
separation of an insoluble solid from a liquid mixture using a semipermeable
membrane like filter paper.
In decantation, the large particles of insoluble solid are separated from the
(6) mixture. (7) separates the soluble solid from the liquid
component of the solution by evaporating the liquid substance.
