Answer 4

Filtration separates solids and liquids

Question 5

Identify what state of matter does evaporation (and crystallisation) separate

Answer 5

Evaporation (and Crystallisation) separates dissolved solids in liquids

Question 6

Identify what state of matter does distillation separate

Answer 6

Distillation separates liquids

Question 7

Answer 7

Fractional Distillation separates liquids

Question 8

Identify what state of matter does sedimentation separate

Answer 8

Sedimentation separates solids and liquids

Question 9

Identify what state of matter does decantation separate

Answer 9

Decantation separates solids and liquids or immiscible liquids

Question 10

Identify which property evaporation (and crystallisation) uses to separate substances

Answer 10

Evaporation (crystallisation) separates substances based on boiling points

Question 11

Identify which property distillation uses to separate substances

Answer 11

Distillation separates substances based on boiling points

Question 12

Identify which property fractional distillation uses to separate substances

Answer 12

Fractional distillation separates substances based on boiling points (not as extreme as distillation)

Question 13

Identify what state of matter does the use of a separating funnel separate

Answer 13

Separating Funnel separates liquids

Question 14

Identify which property sedimentation uses to separate substances

Answer 14

Sedimentation separates substances based on density

Question 15

Identify which property decantation uses to separate substances

Answer 15

Decantation separates substances based on density and immiscibility of substances

Question 16

Identify which property separating funnel uses to separate substances

Answer 16

Separating Funnel separates substances based on density and immiscibility of substances

Question 17

Identify what state of matter does adding a solvent, then filtering separate

Answer 17

Adding a solvent, then filtering separates solids

Question 18

Identify what state of matter does centrifuging separate

Answer 18

Centrifuging separates liquids from denser substances, liquids and solids

Question 19

Identify what state of matter does chromatography separate

Answer 19

Chromatography separates liquids

Question 20

Identify which property adding a solvent, then filtering uses to separate substances

Answer 20

Adding a solvent, then filtering separates substances based on solubility

Question 21

Identify which property magnetic separation uses to separate substances

Answer 21

Magnetic Separation separates substances based on magnetic properties

Question 22

Identify which property centrifuging uses to separate substances

Answer 22

Centrifuging separates substances based on density

Question 23

Identify which property chromatography uses to separate substances

Answer 23

Chromatography separates substances based on absorption and solubility; lower absorption and higher solubility means a higher velocity

Question 24

Identify the phenomenon that makes chromatography possible. Define the phenomenon

Answer 24

Chromatography is possible due to a phenomenon, capillary action, which is the movement of liquids within the spaces of a porous material due to the forces of adhesion, cohesion, and surface tension and without the assistance of external forces
