D)surface tension

Question

Quizplus · Accepted Answer

Surface tension is a property of liquids that arises due to the cohesive forces between liquid molecules at the surface, which is not applicable to gases. Gases do not have a free surface that can deform under tension, making the concept of surface tension irrelevant for materials in the gas state.
