Surface tension is the tendency of liquid surfaces at rest to shrink into the minimum surface area possible. Surface tension is what allows objects with a higher density than water such as razor blades and insects (e.g. water striders ) to float on a water surface without becoming even partly submerged.
4 de may. de 2024 · Learn what surface tension is, how it affects the shape and behaviour of liquids, and how it varies among different substances. Explore the history and applications of surface tension with Britannica's articles and videos.
27 de feb. de 2020 · La tensión superficial es la resistencia de la superficie de un líquido a deformarse. Aprende qué es, cómo se mide, qué factores la afectan y qué fenómenos físicos se explican con ella.
La tensión superficial de un líquido es la cantidad de energía necesaria para aumentar su superficie por unidad de área. 1 Esta definición implica que el líquido presenta una resistencia al aumentar su superficie, lo que en efecto permite a algunos insectos poder desplazarse por la superficie del agua sin hundirse.
Surface tension is the energy, or work, required to increase the surface area of a liquid due to intermolecular forces. Since these intermolecular forces vary depending on the nature of the liquid (e.g. water vs. gasoline) or solutes in the liquid (e.g. surfactants like detergent), each solution exhibits differing surface tension properties.
8 years ago. Water has a high surface tension because the water molecules on the surface are pulled together by strong hydrogen bonds. That means a drop of water will "want" to have the smallest possible surface area. The shape that has the smallest possible area for a given volume is a sphere.
Learn about the cohesive forces between liquid molecules that cause surface tension, and how it affects various phenomena such as walking on water, capillary action, and cleaning. Explore the effects of temperature, soaps, and disinfectants on surface tension with graphs and examples.
