At 250C, the interfacial tension between water and n – octyl alcohol is 8.50 dyne/cm. if the surface tension of n-octyl is 27.53 dyne/cm and that of the water is 72.75 dyne/cm, predict whether water spreads on the alcohol by calculating a) Work of cohesion of n-octyl b) Work of adhesion and c) the spreading coefficient of water on the alcohol. Will alcohol spread on water?
