Vedclass · Answer

(A) Surface tension is caused by the cohesive forces between molecules at the surface of a liquid. As the temperature of a liquid increases, the kinetic energy of the molecules increases, which causes the intermolecular distances to increase. This results in a decrease in the strength of the cohesive forces between the molecules. Since surface tension is directly proportional to the cohesive forces, the surface tension of most liquids decreases as the temperature rises.
