“…Metastability in fluids is a common phenomenon whose existence is unequivocally demonstrated by numerous experimental observations (see Skripov, 1973, for a comprehensive review). In addition, property measurements for metastable fluids yield well-defined, reproducible values (Schufle and Venugopalan, 1967;Zheleznyi, 1969;Gillen et al, 1972;Angell et al, 1973;Rasmussen et al, 1973;Chapman et al, 1975;Speedy and Angell, 1976;Richards and Trevena, 1976;Trinh and Apfel, 1978;Henderson and Speedy, 1980). These and other experimental studies unfortunately have not been accompanied by a corresponding progress in our theoretical understanding of metastability from a fundamental (molecular) viewpoint: lattice models with short range interactions, which are otherwise more realistic than mean field approaches for the quantitative description of matter under conditions where fluctuations are important, do not exhibit analytic continuation into the metastable region.…”

If a given liquid exhibits a density maximum anywhere in its phase diagram, thermodynamic consistency dictates that such a point cannot be isolated: a density maxima locus must necessarily exist. For a fluid that does not also exhibit density minima, the pressure‐temperature projection of such a locus is negatively sloped, and can only end at a stability limit. There exist two thermodynamically consistent ways in which such an intersection can occur, and they correspond, respectively, to the highest and lowest possible temperatures at which a liquid can exhibit a negative coefficient of thermal expansion. These theoretical predictions are confirmed by experimental observations. The existence of density anomalies anywhere in a liquid's phase diagram is shown to have a profound influence in determining the shape of such a fluid's stability boundary.

“…By the 'O 15 temperature /° C time the water and the heavy water were supercooled 35 °C below their equilibrium freezing points, the specific heat capacities had risen by roughly the specific heat capacity of ice at the melting point. Various detailed explanations for the observed changes in specific volume and specific heat capacity have been advanced (Schufle & Venugopalan 1967;Zheleznyi 1969;. According to preference, it is quite likely that increased supercooling promotes a greater, generalized, non-icelike structuring in the presence of which an increasing fraction of the water molecules tend to form discrete, geometric clusters.…”

The tendencies to non-equilibrium freezing behaviour commonly noted in representative aqueous systems derive from bulk and surface properties according to the circumstances. Supercooling and supersaturation are limited by heterogeneous nucleation in the presence of solid impurities. Homogeneous nucleation has been observed in aqueous systems freed from interfering solids. Once initiated, crystal growth is ofter slowed and, very frequently, terminated with increasing viscosity. Nor does ice first formed always succeed in assuming its most stable crystalline form. Many of the more significant measurements on a given systeatter permitting the simultaneous representation of thermodynamic and non-equilibrium properties. The diagram incorporated equilibrium melting points, heterogeneous nucleation temperatures, homogeneous nucleation temperatures, glass transition and devitrification temperatures, recrystallization temperatures, and, where appropriate, solute solubilities and eutectic temperatures. Taken together, the findings on modle systems aid the identification of the kinetic and thermodynamic factors responsible for the freezing-thawing survival of living cells.

“…Thus, the density of amorphous ice differs according to the preparation method, and can vary from 0.94 g cm -3 for low-density amorphous (LDA) ice to 1.17 g cm -3 for high-density amorphous (HDA) ice [113], while the density of supercooled water decreases from 1.00 to 0.977 g cm -3 as temperature decreases from 0 to -35 °C [114,115].…”

This paper describes the main thermodynamic concepts related to the construction of supplemented phase (or state) diagrams (SPDs) for aqueous solutions containing vitrifying agents used in the cryo-and dehydro-preservation of natural (foods, seeds, etc.) and synthetic (pharmaceuticals) products. It also reviews the empirical and theoretical equations employed to predict equilibrium transitions (ice freezing, solute solubility) and non-equilibrium transitions (glass transition and the extrapolated freezing curve). The comparison with experimental results is restricted to carbohydrate aqueous solutions, because these are the most widely used cryoprotectant agents. The paper identifies the best standard procedure to determine the glass transition curve over the entire water-content scale, and how to determine the temperature and concentration of the maximally freeze-concentrated solution.

Specific volume of liquid water to −40°C

Abstract: The specific volume of water has been measured at temperatures extending down to approximately −40°C by holding the water in fine capillaries, the smallest of which had a diameter of 4 microns.
