Question

Surface tension of a liquid, with increase in its temperature, (A) increases (B) decreases (C) remains the same (D) first increases and then decreases

Tardigrade Admin · Accepted Answer

The surface tension of liquid decreases with rise in temperature and increase with decrease temperature because cohesive force decrease with increase of molecular thermal activity.
