# incompressible

«incompressible» in Mova's school dictionary: **Not able to be squashed into a smaller space** — its meaning for a pupil, its sense in the lessons and examples.

### part of speech

adjective (incompressible)

### meaning for a pupil

1) Not able to be squashed into a smaller space. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/I/incompressible/#m1)

2) (science) Describing a substance whose volume stays nearly the same when you press on it, such as liquids and solids. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/I/incompressible/#m2)

### sense in the lessons

In science lessons on states of matter, gases are compressible (air in a syringe squashes) but liquids and solids are almost incompressible, because their particles are already close together. This is why hydraulic machines use liquids. Phrases: almost incompressible, incompressible liquid.

### examples

- Water is almost incompressible, so you can't squash it in a syringe. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/I/incompressible/#x1)
- Air is compressible, but bricks are incompressible. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/I/incompressible/#x2)
- Hydraulic brakes work because oil is nearly incompressible. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/I/incompressible/#x3)
- We pushed the plunger: the water stayed the same; it's incompressible. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/I/incompressible/#x4)
- Solids are incompressible because their particles are packed tight. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/I/incompressible/#x5)
- We squeezed a sealed bottle of water and found it almost incompressible. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/I/incompressible/#x6)

### note

Opposite: «compressible». Strictly, nothing is perfectly incompressible; liquids squash a tiny bit under huge pressure, so science says «nearly incompressible».
