Popis: International audience; In this work, experimental measurements of isobaric heat capacity as well as speed of sound were performed in the compressed liquid phase of n-undecane from 303.15 to 373.15 K and for pressures ranging up to 60 MPa. These results were used to estimate various thermophysical properties such as density, isentropic compressibility and isochoric heat capacity in the same ranges of pressure and temperature. All these sets of data allow checking the thermodynamic consistency between calorimetric, acoustic and volumetric properties.
