DETERMINATION OF THE THERMODYNAMIC PROPERTIES OF LIQUID n-HEXADECANE FROM THE MEASUREMENTS OF THE VELOCITY OF SOUND
T. S. Khasanshin, V. S. Samuilov, and A. P. Shchemelev UDC 536.7:547.217.9 The density, the isobaric expansion coefficient, the specific heats at constant pressure and constant volume, and the isothermal compressibility coefficient of liquid n-hexadecane have been calculated in the range of temperatures 298-433 K and pressures 0.1-140 MPa from the data on the velocity of sound. The coefficients of the Tate equation in the above parametric range have been determined. The table of the thermodynamic properties of n-hexadecane has been presented. Keywords: n-hexadecane, velocity of sound, density, specific heat, isobaric expansion coefficient.
