methods of seperation (physical change)

29
What is filtration used for?
Separating insoluble solids from liquids in heterogeneous mixtures.
Example: sand and water.

30
What is distillation used for?
Separating components of a homogeneous mixture based on different boiling points.
Example: separating water from saltwater.

31
What is evaporation used for?
Separating a dissolved solid from a liquid by evaporating the liquid.
Example: getting salt from saltwater.

32
What is chromatography used for?
Separating mixtures of substances based on how they move through a medium.
Example: separating ink pigments.

33
What is decanting?
Carefully pouring off a liquid to separate it from a denser solid that has settled.
Example: separating water from mud.

34
What is centrifugation?
Using rapid spinning to separate substances based on density.
Example: separating blood components.

35
What is magnetism used for in separation?
Separating magnetic materials from non-magnetic ones.
Example: iron filings from sand.

36
What is crystallization?
Forming solid crystals from a solution as the solvent evaporates.
Example: forming sugar crystals from syrup.
