incompressible
Resists volume reduction
Incompressible describes something that cannot be compressed—squeezed into a smaller volume.
In physics and engineering, incompressible fluids like water maintain constant density regardless of pressure, unlike gases which compress readily: For most practical purposes, we treat water as incompressible.
The term appears in fluid dynamics, materials science, and discussions of hydraulic systems.
