reduced pressure is a dimensionless quantity.

all gases have compressibility factor of nearly unity at high temperature and pressures.

the van der Waal's gas three roots of identical values at the critical point.

in case of real gases, the deviation from the ideal conditions is maximum when each of the reduced pressure and reduced temperature has unit value.
