B 16 Baidakov, V. G. Surface tension of dimethyl ether in the temperature range 120–214 K [Electronic resource] / V. G. Baidakov, A. M. Kaverin, K. A.

Рубрики: ФИЗИКА Кл.слова (ненормированные): CAPILLARY CONSTANT -- DIMETHYL ETHER -- SURFACE TENSION Аннотация: The capillary constant a 2 was measured by the differential capillary method of surface tension measurement. The surface tension σ of dimethyl ether was calculated. The experiments were performed both above the triple point temperature (T t = 131.66 K) and below it in the range in which the coexisting liquid and gas are metastable. Equations that approximate the temperature dependences of a 2 and σ were suggested. The excess surface entropy and energy were determined. The surface entropy had a maximum at T ≈ 190 K. \\\\expert2\\nbo\\Russian Journal of Physical Chemistry A, Focus on Chemistry\\2015, V.89, N 1, p.782-785.pdf |
