The directed contracting force which attracts the molecules at the surface of a liquid towards the interior of the liquid is surface tension. The surface tension of liquids depends on the composition of the vapour phase.
WebMar 7, 2024 · Surface tension occurs due to the difference in inner and outer forces experienced by the molecules at the surface. Hence, the more the surface tension the more round the bead of the liquid becomes. Correct answer: The surface tension of mercury at normal temperature compared to that of water is (a) more.
