Decane is an alkane hydrocarbon with the chemical formula C 10 H 22.Although 75 structural isomers are possible for decane, the term usually refers to the normal-decane ("n-decane"), with the formula CH 3 (CH 2) 8 CH 3.All isomers, however, exhibit similar properties and little attention is paid to the composition. Surface tension is the energy required to stretch a unit change of surface area - and the surface tension will form a drop of liquid to a sphere since the sphere offers the smallest area for a definite volume.

Pentane and octane only exhibit London dispersion forces. pentanal. The strength of London dispersion forces depends on the total number of electrons and the area over which they are spread. 0 0. 4 years ago. Lv 4. Surface tension plays a significant role in several indus-tries, such as paints, detergents, agrochemicals, and pe-troleum. New experimental results are reported for the surface tension of normal pentane, hexane, heptane, and octane. High-Pressure and High-Temperature Density Measurements of n-Pentane, n-Octane, 2,2,4-Trimethylpentane, Cyclooctane, n-Decane, and Toluene A thesis submitted in partial fulfillment of the requirements for the degree of Master of The overall tendency of the viscosity variation was similar regardless of the experimental method. The surface tension of the hydrocarbon liquids in the table does increase from hexane to decane, but only by a rather small amount (20 % overall, compared to the doubling of viscosity). pentane.

Surface Tension of Hexane. … Surface tension is caused by the inward attraction of molecules at a boundary. Viscosity¶ E. K. Michailidou, M. J. Assael, M. L. Huber, and R. A. Perkins. With higher IMFs, you get greater surface tension and greater viscosity (since the liquid molecules are more attracted to each other) In order of decreasing IMF: (and thus decreasing viscosity/surface tension) pentanol. Describe how the number of molecules of water in the liquid and gas phases is related to equilibrium vapor pressure. In extraction processes, oil has to travel through capillary channels, and this type of flow is strongly dominated by surface tension effects. Hexane is a non-polar molecule, the only intermolecular forces acting between hexane molecules in the liquid will be the weakest of all the intermolecular forces, London forces (also known as dispersion forces). Of seven tissues studied, n-pentane showed the highest solublility in adipose tissue followed by brain, liver, muscle, kidney, lung, and heart.
