PPT – 1. The adhesion and cohesion forces, both vary in their strengths. Attractive forces between molecules of the same type are called cohesive forces. Adhesive forces cause dissimilar surfaces to get attracted to each other. Water. Surface tension is the result of cohesive forces between adjacent molecules. When liquid is placed on a smooth surface, the relative strengths of the cohesive and adhesive forces acting on that liquid determine the shape it will take (and whether or not it will wet the surface).
