V. Physical Methods of Separating Mixtures

Question 1

Mixtures

Answer 1

Combinations of two or more pure substances that are not combined chemically

Question 2

Magnets

Answer 2

The separation of mixtures are being done through the use of magnets

Question 3

What special property do magnets have?

Answer 3

Magnetism

Question 4

What does magnetism attract?

Answer 4

Iron and steel

Question 5

Decantation

Answer 5

Works because different
components have different
densities, and the denser
component settles at the bottom

Question 6

Evaporation

Answer 6

Process used to separate a
dissolved solid from a liquid mixture, the liquid component of the mixture turns into gas due to high temperature, leaving the solid component behind

Question 7

Filtration

Answer 7

Works because the filter has tiny holes that allow a liquid or gas to pass through while trapping the solid particles

Question 8

Sublimation

Answer 8

A process where a substance goes
from a solid directly to a gas when
heated, without becoming a liquid
in between

Question 9

Distillation

Answer 9

A process that uses heat to
separate the components of a mixture based on their different boiling points, the component with the lower boiling point will vaporize first when it reaches its boiling point

Question 10

Chromatography

Answer 10

A technique used to separate the components of a mixture based on how fast they move through a special paper or column, different components will move at different speeds based on their affinity for the paper and solvent
