Kinematic Viscosity of Liquid Rubidium from 67° to 688° C.

Abstract

perature behavior as well as a very strong influence of pressure on solubility. The smoothed atmospheric pressure results were so low that they could not be plotted on Figure 4.The density results are compared with data for the pure solvents in Figures 5 and 6. As shown, a t low temperatures, the small amount of dissolved solute causes a small decrease in solvent density. As temperature increases, solubility increases, and the density departure becomes larger.

Calculation of Thermal Pressure Coefficient of Lithium Fluid by pVT Data

“…The most straightforward way to derive the thermal pressure coefficient is the calculation of thermal pressure coefficient with the use of the principle of corresponding states which covers wide temperature and pressure ranges. The principle of corresponding states calls for the reduced thermal pressure at a given reduced temperature ISRN Physical Chemistry TPC Helmholtz TPC (1) TPC (2) TPC ( The experimental values of thermal pressure coefficient versus density for Li fluid are compared with thermal pressure coefficient using the LIR (1) , LIR (2) , and LIR (3) at 600 K.…”

“…However, as density increases, molecular interactions become increasingly important, and the principle of corresponding states fails. The leading term of this correlation function is the thermal pressure TPC Helmholtz TPC (1) TPC (2) TPC ( The experimental values of thermal pressure coefficient versus density for Li fluid are compared with thermal pressure coefficient using the LIR (1) , LIR (2) , and LIR (3) at 1600 K.…”

“…Based on (17), to obtain thermal pressure coefficient, it is necessary to determine values Figures 7 and 8 show the experimental values of thermal pressure coefficient versus density for liquid lithium that are compared with thermal pressure coefficient using the TPC (1) , TPC (2) , and TPC (3) at 600 and 1600 K, respectively. Figure 5: The experimental values of thermal pressure coefficient versus density for Li fluid are compared with thermal pressure coefficient using the LIR (1) and LIR (2) at 600 K.…”

“…These problems have led us to try to establish a function for the accurate calculation of thermal pressure coefficients of the lithium fluid based on linear isotherm regularity equation of state theory. In contrast, Figures 8 and 9 show the experimental values of thermal pressure coefficient versus density for liquid lithium that are compared with thermal pressure coefficient using the TPC (1) , TPC (2) , and TPC (3) at 600 and 1600 K, respectively. Although all three models capture the qualitative features for lithium of liquid, only the calculated values of thermal pressure coefficient using the TPC (3) model produce quantitative agreement.…”

“…The element serves no apparent vital biological function, since animals and plants survive in good health without it. The lithium ion Li + administered as any of several lithium salts has proved to be useful as a moodstabilizing drug due to neurological effects of the ion in the human body [1][2][3].…”
