Abstract

Sound velocities in aqueous 0.1, 0.5 and 1.0 mol·kg^-1 lithium chloride solutions were determined at 1 K temperature intervals from 278.15 to 323.15 K. These velocities served to evaluate the isentropic compressibilities κ _S , the isothermal compressibilities κ _T , the apparent molar compressibilities K _2,φ , the isochoric thermal pressure coefficients (∂ P/∂ T) _V , the change of cubic expansion coefficients with pressure at constant temperature (∂ α/∂ P) _T , and the changes of heat capacities C _V with volume (∂ C _V /∂ V) _T and C _P with pressure (∂ C _P /∂ P) _T .
