4) The surface tension of the liquid is equal to bj = 250 mJ/m2, and the contact angle of the solid surface with this liquid is 1600. How did the work of cohesion of the liquid and the work of adhesion of the phases change after the introduction of a surfactant into the liquid, if bj decreased to 130 mJ/m2, and the contact angle reduced to 800?
