Ultrasonic Propagation in Liquids. II. Theoretical Study of the Free Volume Model of the Liquid State

摘要: The free volume theory of liquids is applied to problems connected with sound propagation. equation state derived by Tonks for assemblies hard elastic spheres may be written pVa≅3NkT, where the available Va difference between actual and corresponding closest possible packing. It shown that molar approximately given increase in a substance on heating from 0°K temperature considered, so pictorial concept has real physical basis. Using equation, expressions are velocity, pressure coefficients velocity. These compared experimental results. Expressions also cubic expansion coefficient specific heats model. Herzfeld‐Rice derivation absorption caused phase shifts vibrational heat carri...
