Show Abstract
A review is made of measurements of the effect of temperature, pressure, isotopic composition, and dissolved atmospheric gases on the density of liquid water at temperatures to 100°C. The molar volume is expanded as a multiple power series in the variables, and the coefficients determined. A number of gaps become evident in our knowledge of properties that are within the capacity of current measurements. For example, there appears to be no measurement of the effect of oxygen isotopes on the compressibility. Data on the thermal expansion of D2O are strikingly inconsistent. The partial molar volumes of dissolved gases are only sketchily known. At O°C, equilibration with the oxygen, nitrogen, and argon of the atmosphere lowers the density about 3 p.p.m., while atmospheric carbon dioxide raises it about 0.3 p.p.m. Appendix I discusses the care needed to obtain various degrees of precision in practical density measurements, and the effect of isotopic uncertainties on them. Appendix II treats the representation of the equation of state of water at slightly higher pressures.

Show Abstract
The paper traces the development of our knowledge of the viscosity of water and steam over the last decade, that is over the period of intense experimental and analytic activity which separates the promulgation of the 1964 Supplementary Release on Transport Properties of the Sixth ICPS from the recently announced Release on Dynamic Viscosity of Water Substance. As a result of this work, which was largely stimulated by the activities of the International Association for the Properties of Steam, the new internationally recognized skeleton table and the internationally recommended interpolation equations cover the wide range of pressures and temperatures of 0–100 MPa and 0–800°C.

A correlation of the existing viscosity and thermal conductivity data of gaseous and liquid ethane

Show Abstract
Data for the viscosity and thermal conductivity coefficients of ethane have been evaluated and represented by an empirical function. Tables of values have been prepared for the range 200–500 K, for pressure to 75 MPa(?750 atm). The tables include an estimate of the anomalous contribution to the thermal conductivity in the neighborhood of the critical point. The estimated uncertainties of the tabular values are ±5% and ±8% for the viscosity and thermal conductivity coefficient, respectively.

Show Abstract
The elastic constants of zinc are compiled and reviewed; one hundred references are cited. The included elastic constants are: Young’s modulus, shear modulus, bulk modulus, compressibility, Poisson’s ratio, second‐order single‐crystal elastic stiffness and compliances, and third‐order, elastic stiffness. Temperature and elastic‐anisotropy effects are also reviewed. Other topics are: sound velocities, elastic Debye temperature, Cauchy relationships, elastic stability, pressure effects, and theoretical studies. New polycrystalline data are computed from single‐crystal data by tensor‐averaging methods.

Show Abstract
The results of the published work on the high pressure‐high temperature properties of the AB‐type compounds have been compiled and evaluated. All pressure studies above the range of 1 kilobar have been included with an emphasis on the accurate characterization of the solid‐solid phase boundaries and the experimental melting curves. Whenever x‐ray diffraction data are available for the high pressure phases, they have also been reviewed. Phase diagrams are included for all compounds in which measurement of more than one point along the phase boundary was made. This review discusses a total of 87 compounds and 212 distinct high pressure‐high temperature phases.

Show Abstract
The energy levels of the manganese atom in all of its stages of ionization, as derived from the analyses of atomic spectra, have been compiled. In cases where only line classification are given in the literature, level values have been derived. The percentages for the two leading components of the calculated eigenvectors of the levels are given where available. Ionization energies and g‐values are also given.
