Abstract
Yang-Yang (YY) and singular diameter critical anomalies arise in exactly soluble compressible cell gas (CCG) models that obey complete scaling with pressure mixing. Thus, on the critical isochore , diverges as when while where . When the discrete local CCG cell volumes fluctuate freely, the YY ratio may take any value but “anticorrelated” free volumes are needed for . More general decorated CCGs, including “hydrogen bonding” water models, illuminate energy-volume coupling as relevant to .
