Vedclass · Answer

(C) The magnitude of the surface tension of a liquid depends on the attractive forces between the molecules. When the attractive forces are large,the surface tension is large. An increase in temperature increases the kinetic energy of the molecules,which reduces the effectiveness of intermolecular attraction. Consequently,the surface tension decreases as the temperature is raised.
