Problem: Identify the true statements about surface tension. Molecules along the surface of a liquid behave differently than those in the bulk liquid. Mercury has a lower surface tension than water. Cohesive forces attract the molecules of the liquid to one another. Surface tension increases as the temperature of the liquid rises. Water forming a droplet as it falls from a faucet is a primary example of surface tension.
