An investigation of the validity of the free volume theory of liquid has been undertaken on the basis of the theory of correlation functions. A formula for free volume without use of a geometrical model has been proposed and discussed. The magnitude of equivalent free volumes obtained from the formula has been found to be nearly equal to that calculated from the entropy of vaporization by means of the free volume theory. The results give support to the physical reality of the concept of free volumes. The communal entropy deduced agrees with that obtained by an expansion formula to the first order of density. A formula for compressibility has also been derived, which gives satisfactory results in comparison with observed data.
