In general, surface tension decreases when temperature increases because cohesive forces decrease with an increase of molecular thermal activity.

Answer 2

Answer:

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 of liquid molecules that they have at the interface
