3. The surface tension of the liquid is equal to σl = 240 mJ/m2, and the contact angle of the solid surface with this liquid is equal to 1400. How did the work of liquid cohesion and the work of phase adhesion change after introducing a surfactant into the liquid, if σl decreased to 110 mJ/m2, and the contact angle decreased to 600?
