Yeah, I think they don't change volume under pressure, right?

Root Explanation

Noncompressible → It is formed from "non-" (meaning not) and "compressible" (from Latin "comprimere", meaning to press together). The word "noncompressible" means not able to be pressed together or compressed.

Memory Tip

Think of 'not' ('non-') being added to 'press together' ('compressible') — that's why noncompressible means something that cannot be compressed.
