Surface tension is the tendency for molecules at the surface of a liquid to hold

Question

Surface tension is the tendency for molecules at the surface of a liquid to hold together rate at which molecules move into and out of the surface of a liquid tendency for a molecule to pack into spherical shapes tendency for the adhesive forces of a molecule to overcome the cohesive forces none of the above Why does soap decrease the surface tension of water? It keeps water molecules away from the surface. It increases the capillary action of the water. It increases the ionic content of the water. It decreases the amount of intermolecular attraction between the water molecules. none of the above
