Label each target to indicate if the interaction between the molecules inside the rectangle contributes to surface tension (T), adhesion (A), or cohesion (C).
Note that one target should be left blank because the molecules inside that rectangle are not involved in any of these interactions.
Surface tension most commonly occurs at air-water interfaces, where it resists breakage of the surface. Hydrogen bonds tend to pull water molecules at the surface together, reducing the curvature of the surface.
Cohesion tends to keep water molecules that are away from surfaces from separating.
Adhesion makes water stick to hydrophilic surfaces, such as cell walls.
