Question

Why surface tension decreases with increase in concentration?

Answer 1

Answer:

In 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.

Answer 2

$\huge \fbox \blue{Answer}$

The surface tension can be determined . Hence, study shows that surface tension decreases as we increase the concentration of gum solution. This occurs due to larger interaction between molecules of liquid than molecules present in air or in non-polar solvents.
