Web1. Definition of Surface Tension: The force with which the surface molecules are held together is called surface tension. 2. Explanation for Surface Tension: The interior molecules of a homogeneous liquid are equally attracted in all directions by surrounding molecules. They are free to move in all directions. WebApr 17, 2024 · Surface tension is a force which causes a layer of liquid to behave like an elastic sheet or skin. Molecules of water are more attracted to each other than other molecules, as water is a polar molecule. The positive hydrogen end of one molecule is attracted to the negative oxygen end of another water molecule.

WebSurfactants are chemical compounds that decrease the surface tension or interfacial tension between two liquids, a liquid and a gas, or a liquid and a solid.Surfactants may function as emulsifiers, wetting agents, detergents, foaming agents, or dispersants.The word "surfactant" is a blend of surface-active agent, coined c. 1950.. Agents that increase … WebDec 20, 2024 · Surface tension is caused by liquid particle intermolecular forces such as the Van der Waals force. The molecules on the surface are drawn to the liquid’s bottom. Because of cohesive forces, a molecule is dragged in all directions equally by neighboring liquid molecules, resulting in a net force of zero. As the molecules near the surface are ...
