It decreases.

Vedclass · Answer

(B) Surface tension is defined as the force per unit length acting on the surface of a liquid. It arises due to the cohesive forces between the molecules of the liquid. As the temperature of a liquid increases,the kinetic energy of the molecules increases,which weakens the intermolecular cohesive forces. Since surface tension is directly related to the strength of these cohesive forces,an increase in temperature leads to a decrease in surface tension. Therefore,the correct answer is that surface tension decreases with an increase in temperature.
