2. J. S EPARATING M IXTURES Filtration Separates a solid from the liquid in a heterogeneous mixture using a porous barrier. Example: A colander is used to separate pasta from the water in which it was cooked.

4. J. S EPARATING M IXTURES C ONT. Distillation Separates mixtures based on difference in boiling points of components in the mixture. A liquid is boiled to produce a vapor that is then condensed into a liquid. Example: Distilled Water

5. J. S EPARATING M IXTURES C ONT. Crystallization Separates mixtures by forming pure solid particles in a solution containing the dissolved solute. Example: Rock candy.

6. J. S EPARATING M IXTURES C ONT. Chromatography Separates the components of a mixture because components travel across a surface at different rates.
