### part of speech

noun (distillation, uncountable; a distillation, distillations)

### meaning for a pupil

1) Distillation is a way of making a liquid pure by heating it until it turns into vapour (gas), then cooling the vapour so it turns back into liquid and collecting it. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/D/distillation/#m1)

2) A distillation is the most important part of something, kept after the rest is taken away. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/D/distillation/#m2)

### sense in the lessons

In science lessons, distillation is a method of separating mixtures: salty water can be distilled to get pure water, because the water evaporates and condenses but the salt stays behind. It uses evaporation and condensation. Phrases: simple distillation, fractional distillation, distilled water.

### examples

- Distillation can turn sea water into drinking water. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/D/distillation/#x1)
- In distillation, the water evaporates and then condenses. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/D/distillation/#x2)
- The salt is left behind after distillation. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/D/distillation/#x3)
- Distilled water is very pure. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/D/distillation/#x4)

### note

Mostly uncountable. Verb: distil (British) or distill (American); the noun «distillation» is spelt with double l everywhere. Distillation is not the same as filtering: filtering removes solid bits, but it cannot remove salt dissolved in water.

### In the corpora

- [Distillation is boiling a liquid and cooling the steam back to liquid; the drops are pure water, and the salt stays behind.](https://md.mova.elamur.ai/free/en/corpora/school/chemistry/8-separating-mixtures/12/)
- [Ships and some dry countries make drinking water from seawater by distillation and other methods.](https://md.mova.elamur.ai/free/en/corpora/school/chemistry/8-separating-mixtures/13/)
- [To get pure water from salty water, the vapour must be collected and cooled so it condenses; this is called distillation.](https://md.mova.elamur.ai/free/en/corpora/school/world/19-mixtures-and-separating/14/)
