Quiz on distillation and sublimation methods.

by YAKILI LMS
1

Paper chromatography uses gravity alone to move the solvent up the paper.

2

In distillation, the mixture is cooled to separate solids by filtration.

3

Sublimation is when a solid turns directly into a gas.

4

Distillation is primarily used to crystallize a solid from a solution.

5

Paper chromatography requires heating the paper to 1000°C.

6

Sublimation is a process where a liquid becomes a solid via deposition.

7

Paper chromatography works best with a single component and cannot separate mixtures.

8

Distillation produces multiple different products by chemical change.

9

Paper chromatography is used to separate mixtures based on solubility and paper affinity.

10

Sublimation reduces a solid’s mass as it turns into gas.

11

Sublimation changes a solid to a liquid first before becoming gas.

12

Distillation can separate gases with close boiling points by freezing them.

13

Distillation is a form of chemical reaction that changes the substance.

14

Paper chromatography can separate all types of mixtures equally well.

15

In distillation, the liquid with higher boiling point distills first.

16

Distillation separates liquids with different boiling points.

17

Sublimation can occur at any temperature without a pressure change.

18

Sublimation will occur at any temperature if pressure is high enough.

19

Paper chromatography is identical to paper filtration in mechanism.

20

Sublimation is the process of a liquid turning into a solid directly.

21

Sublimation occurs when a gas turns into a liquid.

22

In distillation, a solid is dissolved in a solvent to form a solution.

23

Sublimation is only possible at very high pressures.

24

Sublimation changes a liquid directly into a solid.

25

Distillation is a filtration technique that traps solids in a filter.

26

Sublimation always produces a colorless gas.

27

In distillation, the mixture remains completely unchanged after separation.

28

Paper chromatography uses a chromatography column filled with metal beads.

29

Distillation reduces a liquid to a solid through evaporation.

30

Paper chromatography is primarily used for measuring viscosity.

31

In sublimation, a gas condenses directly into a solid.

32

Paper chromatography is used to measure the density of liquids.

33

Paper chromatography is ineffective for separating dyes in ink.

34

Paper chromatography cannot identify substances in a mixture.

35

Paper chromatography requires high vacuum to function correctly.

36

Paper chromatography relies solely on color to identify components, not their movement.

37

Sublimation only occurs when the solid has a boiling point below 0°C.

38

Distillation is used to increase the number of components in a mixture.

39

In distillation, impurities are removed through chemical reaction.

40

Distillation is used to grind mixtures into smaller pieces before separation.

41

Sublimation turns a solid into a liquid before becoming a gas.

42

Sublimation requires the substance to melt before turning into gas.

43

Sublimation requires the substance to be dissolved in water.

44

In distillation, you distill the mixture but do not collect any fractions.

45

Sublimation produces a liquid from a gas under standard conditions.

46

Distillation cannot separate liquids with different boiling points.

47

Distillation relies on magnetic properties of substances to separate them.

48

Paper chromatography cannot separate dyes from inks.

49

Paper chromatography uses magnetic fields to separate components.

50

Paper chromatography is a method to measure pH levels of liquids.
