Question

what is surface tension​

Answer 1

Answer:

HAVE YOU EVER overfilled your glass of water so that the water level is higher than the glass and still the water remains in the glass? This seemingly gravity-defying observation indicates there is a force that wants to keep the liquid together. This force is called the surface tension.

Explanation:

Imagine the interface between a liquid and a gas. Most of the molecules in both phases are in the bulk but some of the molecules are at the interface facing the other phase. The molecules in the bulk interact similarly with all the molecules surrounding them – there is a similar pull to all directions resulting in zero net force.

Answer 2

hi mate ,

»»»» the tension of the surface film : of a liquid caused by the attraction of the particles in the surface layer by the bulk of the liquid, which tends to minimize surface area.

• »»»»Surface Tension: "The property of the surface of a liquid that allows it to resist an external force, due to the cohesive nature of its molecules.
• »»»»" It seems to defy the laws of physics, but a paper clip made of steel can indeed float on the water surface.
