compressibility
Shrinkage under pressure
Compressibility is how much something can be squeezed into a smaller volume.
Gases have high compressibility; liquids and solids have very little.
In physics and engineering, compressibility is measured as the ratio of volume change to pressure change.
The term extends to data: The compressibility of video files depends on how much redundant information they contain.
