Surface tension is thought to be due to:
A)surface area trying to increase
B)air absorbed on the surface
C)solute concentrated on the surface
D)surface molecules having lower energy than bulk molecules
E)surface molecules having higher energy than molecules in the bulk

Question

Quizplus · Accepted Answer

Surface tension is primarily due to the fact that molecules at the surface of a liquid have higher energy than those in the bulk. This is because molecules at the surface are not surrounded by as many neighboring molecules, which results in a net inward force and leads to the phenomenon of surface tension.
