The surface tension of n-pentane, n-heptane and some of their mixtures were measured at 91.3 kPa and T = (283.15 to 323.15) K by the maximum bubble pressure method. A. G. Badaliyan, Density and Viscosity of n-Octane from the Triple Point to the Dissociation Temperature, Candidate dissertation (Grozny Petroleum Institute, 1987). The pentanes are molecular, and certainly they are non-polar, and hence addition of "n-pentane" to water gives rise to two immiscible layers, with the LESS dense pentane floating on top of the funnel.

The comparison between the mixture surface tension results and those calculated by the model indicate that the new proposed model can be satisfactorily used for calculating the surface tension of n-pentane, n-heptane and their mixtures. Additionally, since octane has a higher surface tension, they soon discover the macroscopic effects of having different surface tensions. Phys. Uspekhi F. D. Rossini, K. S. Pitzer, R. L. Arnett, R.
