Nagesh Sharma Surface Tension of n-Butanol and Amount Adsorbed 2017-09-25 104550601 Abstract A surface is an interface between two different phases and is treated in the same way as all other phases of matter. For some reason, we encountered difficulty seeing the meniscus of the capillary tube overestimates surface tensions, i.e. World Scientific Publishing Co., Hackensack, Oliveira MLN, Malagoni RA, Fehr M, Franco Júnior MR (2008) Obtaining solubility data from a liquid–liquid equilibrium cell.

It has been known that few high-carbon alcohol-aqueous solutions exhibit an opposite behavior of the surface tension increasing with regard to temperature, such that the Marangoni flow moves towards the hot surface (self-rewetting effect). It was found from this study that the aqueous solutions with higher-carbon alcohols exhibit a weak self-rewetting behavior, such that the surface tensions remain constant or slightly increases above about 60 °C.
