Identify the true statements about surface tension.
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.

Surface Tension and Bubbles Surface tension is a force caused by the attraction of liquid molecules on a boundary surface for each other. It acts tangential to the surface and is modeled as a single number, the surface tension Consider a square film on a wire frame. The bottom edge is movable and, when the frame is vertical, as shown, the surface tension of the film pulls...
