The surface tension σ of aqueous solutions of normal alcohols (from methanol to n-butanol) was measured in the temperature range between 278 and 303 K using the Wilhelmy plate method. The surface entropies are calculated. The results are interpreted in terms of specific interactions of the hydrophobic parts of the molecules adsorbed at the interface. It is concluded that increasing surface concentration of alcohol molecules causes their rearrangement at the surface, similar to phase transition. This process depends on the symmetry of molecules.
