It stems from the cohesive forces between molecules at the surface of a liquid. These attractive forces create a sort of &#8220;skin&#8221; on the liquid surface, allowing insects to float and certain objects to &#8220;float&#8221; on water. The origin of surface tension can be traced back to the molecular-level interactions that occur between liquid molecules.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335551550&quot;:0,&quot;335551620&quot;:0,&quot;335559685&quot;:-20,&quot;335559737&quot;:-20,&quot;335559739&quot;:160,&quot;335559740&quot;:279}\">\u00a0<\/span><\/p>\n<h3 aria-level=\"2\"><strong>Cohesion and Surface Tension Relation<\/strong><\/h3>\n<p><span data-contrast=\"auto\">To truly understand surface tension, we must delve into the concept of cohesion. Cohesion refers to the attraction between molecules of the same substance. In the case of liquids, this cohesive force leads to molecules at the surface being drawn inward, creating a tension that resists external forces. This cohesive force is what gives rise to surface tension.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335551550&quot;:0,&quot;335551620&quot;:0,&quot;335559685&quot;:-20,&quot;335559737&quot;:-20,&quot;335559739&quot;:160,&quot;335559740&quot;:279}\">\u00a0<\/span><\/p>\n<h2 aria-level=\"2\"><strong>What is Surface Tension?<\/strong><\/h2>\n<p><span data-contrast=\"auto\">Surface tension can be defined as the property of a liquid that allows it to resist an external force due to the cohesive nature of its molecules.
