Compilation of thermal properties of hydrogen in its various isotopic and ortho-para modifications

摘要: New developments in science and industry are aided by accurate knowledge of the behavior important substances. The great abundance chemical processes comX pounds which hydrogen is involved make it particular interest. experimental derived data presented here for extend over a large range temperature. Low temperatures required liquid solid, moderate high occur reactions. available thermal H2, HD, D2 liquid, gaseous states have been brought together, including distinctive properties ortho para forms H2 D2. Some not previously published added. include thermodynamic functions ideal gas state, equilibrium constants, viscosity, conductivity with dependence on pressure, vapor pressure* solid-liquid equilibria, specific heats, latent heats. Values state derivatives useful calculations given normal hydrogen, and. related differences between real evaluatedA temperature entropy diagram also given. compiled 38 tables, 33 graphs, numerous equations. sources an extensive bibliography.
