International Thermodynamic Tables of the Fluid State Helium-4 presents the IUPAC Thermodynamic Tables for the thermodynamic properties of helium. The IUPAC Thermodynamic Tables Project has therefore encouraged the critical analysis of the available thermodynamic measurements for helium and their synthesis into tables. This book is divided into three chapters. The first chapter discusses the experimental results and compares with the equations used to generate the tables. These equations are supplemented by a vapor pressure equation, which represents the 1958 He-4 scale of temperature that is defined in terms of the vapor pressure of helium-4. The second chapter are devoted to various equation of state used for the determination of thermodynamic properties. The third chapter contains IUPAC Tables, including their construction, limits, use, and accuracy. This book will be of value to physical chemists and researchers in the field.
