Surface tension and cohesive forces
WebIn general, surface tension decreases when temperature increases because cohesive forces decrease with an increase of molecular thermal activity. The influence of the surrounding environment is due to the adhesive action liquid molecules have at the interface. See a diagram: Effect of temperature on surface tension Surface tension of water WebSurface tension is the common term for this phenomenon. Cohesive forces pull molecules on the surface inward, lowering the surface area. Because they have neighbours on all …
