abstract  ="We present the analysis of the thermal conductivity{,} [small kappa]{,} and heat capacity{,} Cp{,} of a wide variety of liquids{,} covering organic molecular solvents{,} ionic liquids and water-polymer mixtures. These data were obtained from [approximate]0.6 [small mu ]L samples{,} using an experimental development based on the 3[small omega] method{,} capable of the simultaneous measurement of [small kappa] and Cp. In spite of the different type and strength of interactions{,} expected in a priori so different systems{,} the ratio of [small kappa] to the sound velocity is approximately constant for all of them. This is the consequence of a similar atomic density for all these liquids{,} notwithstanding their different molecular structures. This was corroborated experimentally by the observation of a Cp/V [approximate] 1.89 [times] 106 J K-1 m-3 ([approximate]3R/2 per atom){,} for all liquids studied in this work. Finally{,} the very small volume of the sample required in this experimental method is an important advantage for the characterization of systems like nanofluids{,} in which having a large amount of the dispersed phase is sometimes extremely challenging."}
