You might remember my 'Acoustic Ashby chart' where I plotted bulk modulus versus density for various fluids. I've redrawn it with plotly; in due course there'll be a web version where you can hover over points to get the substance name etc, but for now here's a static plot. 
Bulk modulus (inverse of compressibility) provides the restoring force that makes the fluid return to its equiliibrium state when disturbed; density provides the inertia that makes them take time to do so. Liquids are stiff and heavy, gases are floppy and light.
