Compressibility of equal masses of supercritical and water?

[Fanghur]

I have a question relating to supercritical fluids and their compressibility as compared to that same substance in liquid form. Let’s say we took 500g of water and turned it supercritical. Would we be able to then compress that fluid to a greater extent than we would that same mass of liquid water at the equivalent pressures? My instinct tells me no, but I can’t find any actual sources to back that up.

Supercritical water is at a much lower density than liquid water.  It is easily compressible.
