Question

What's the effect on surface tension of temperature

Answer 1

In general, surface tension decreases whentemperature 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 oftemperature on surface tension.
