Specific heats of saturated liquid, along the coexistence path, are useful for co mputing thermodynamic properties thro ughout the compressed liquid phase.We report 86 experimental heat capacities of oxygen for the two-phase system, liquid plus vapor, from the tripl e-poin t to near the criti cal-poi nt and correspo ndin g deriv ed values for the liquid phase.These results are represente d by a formula which ca n be integrated for heat absorbed and for entropy.The chan ges in value of internal e nergy , enthalpy, and e ntropy of the saturated liquid are tabulated from the triple-poin t to th e criti cal-point.
