Surface tension of liquids
A)increases when wetting agents are added.
B)decreases as the liquid temperature increases.
C)is about the same for all liquids.
D)results from a thin molecular membrane beneath the liquid surface.
E)keeps steel ships afloat.

Question

Quizplus · Accepted Answer

Surface tension decreases as the temperature of the liquid increases because the increased kinetic energy of the molecules at higher temperatures reduces the cohesive forces among liquid molecules at the surface.
