| Abstract: | The expression of the pressure coefficient and temperature coefficient of the free length in liquid binary mixtures is obtained. The pressure coefficient and temperature coefficient of the free length are linear function on components. Using the expression, the pressure coefficient and temperature of the free length in liquid binary mixtures can be calculated through the compressibility coefficients, the bulk coefficients of expansion, the molar volumes at absolute zero and weight fractions of two components. |
