WebApr 28, 2024 · Surface tension is a property that makes water and some other liquids seem to have an elastic surface due to high cohesiveness between their molecules. It is a result of water’s polarity and the molecules’ attraction to one another that’s due to the strong hydrogen bonds, and it is what allows some insects and spiders to stand on water.

WebSurface Tension is the ability of a liquid to allow objects to float on top of it. Here’s how it works: The molecules in a liquid pull at each other from all directions. This means they have 0 force. The molecules on the surface of a liquid can’t be pulled in all directions, though, because the top or surface molecules don’t have anything ...

WebThe surface tension of a liquid is mainly a force that mainly acts to reduce the surface area of a liquid.
