Vedclass · Answer

(B) The surface tension of a liquid is caused by the cohesive forces between its molecules. As the temperature of a liquid increases,the kinetic energy of the molecules increases,which causes the average distance between the molecules to increase. This increase in intermolecular distance weakens the cohesive forces between the molecules. Since surface tension is directly proportional to the strength of these cohesive forces,the surface tension of the liquid decreases as the temperature rises.
