Question

Is there any difference between compressibility and compression?

Answer 1

Compressibility is the quality of how much something can be compressed. Compression is how much it IS compressed. The difference between the terms might be likened to the difference between how much your gas tank can hold, and how much it has in it right now.

Answer 2

Yes, compressibility is the extent to which something can be compressed when a unit force (typically 1 N) is applied.

Compression is the measure of reduction in one or more dimensions (length, area, volume) when a force is actually applied.
