The major part of this book consists of tables of the equilibrium thermodynamic properties of fluorine for both the gas and liquid phases and along the saturation and the melting curves. The limits of the tables are 54K to 300K for pressures up to 20MPa. The properties listed are volume, entropy, enthalpy, isobaric heat capacity, compression factor, fugacity-pressure ratio, Joule-Thomson coefficient, ratio of heat capacities and speed of sound as functions of pressure and temperature, and pressure, entropy, internal energy and isochoric heat capacity as functions of density and temperature. The text describes the construction of the equation of state used to calculate the tables together with a critical assessment of the accuracy of all the available experimental data and gives comparisons of the tables with the experimental data. This book will be invaluable to postgraduate chemical and physical scientists and researchers and industrial chemists specializing in the thermodynamic properties of matter
