Surface tension definition: a property of liquids caused by intermolecular forces near the surface leading to the... | Meaning, pronunciation, translations and examples
This term is typically used only when the liquid surface is in contact with gas (such as the air).
Surface tension is a physical property equal to the amount of force per unit area necessary to expand the surface of a liquid. Surface tension is caused by the uneven attraction that molecules at or near the surface of a liquid have for each other. A property of liquids whereby their surfaces behave as if they were covered by a thin, elastic film. The addition of substances called surfactants can reduce the surface tension of a liquid. Liquids tend to acquire the least surface area possible. In the dyeing of textiles, surfactants help the dye penetrate the fabric evenly. When you have a container full of water, the water molecules below the surface are pulled together equally in all directions, but those on top are pulled together more tightly, as they don’t have water molecules above them, this draws them together to form a kind of ‘skin’ which we call surface tension. A falling drop of liquid assumes a spherical form because the ratio of surface area and total free surface energy is the least. The surface can hold up a weight, and the surface of a water droplet holds the droplet together, in a ball shape. Surfactant, substance such as a detergent that, when added to a liquid, reduces its surface tension, thereby increasing its spreading and wetting properties.
Work is needed to increase the surface area e.g. Some insects can run on the surface of water because of this. This activity is a simple demonstration of surface tension. Learn more about surfactants in this article. surface tension meaning: 1. the natural force existing in a liquid that holds its surface together 2. the natural force…. Define surface tension.
