On increasing temperature of a liquid, its surface tension generally

Question

On increasing temperature of a liquid, its surface tension generally (A) Increases (B) Decreases (C) Remains constant (D) First increases and then decreases

Tardigrade Admin · Accepted Answer

On increasing the temperature energy increases hence surface tension decreases. Because surface tension is nothing but some extra energy required by surface molecules to stay at the place.
