How is it look like the phase diagram of a fluid in density-pressure plane? I came across the phase diagram in Pressure-temperature plane most of the time. But I can't find the phase diagram in density-pressure plane.

    $\begingroup$ Isn't the density-pressure plane the same as the specific volume-pressure plane? $\endgroup$ – Chet Miller May 6 at 11:30
  • $\begingroup$ Specific volume is the insverse of density $\endgroup$ – Sushmita Ningombam May 7 at 4:16
  • $\begingroup$ So you are saying that you don’t realize that the PV plane is the same thing as the P density plane? $\endgroup$ – Chet Miller May 7 at 5:01
  • $\begingroup$ How? Volume is inversely proportional to DENSITY. and how the graph can be similar? $\endgroup$ – Sushmita Ningombam May 7 at 9:08
  • $\begingroup$ Are you saying you csn’t figure it out from a PV disgram? $\endgroup$ – Chet Miller May 7 at 9:48
