Interpretation:
The surface tension and the conditions that must exist for it to occur needs to be explained.
Concept introduction:
Surface tension can be defined by cohesive forces.
Answer to Problem 60A
Surface tension is the property of liquid surface to be able to shrink to minimum surface area. Conditions required for surface tension are strong intermolecular forces.
Explanation of Solution
At liquid-air interface surface tension results due to more attraction of liquid molecules because of cohesion more than that of adhesion.
Because of cohesion and adhesion, surface tension results.
