The si unit of surface tension is
Physical units Surface tension, represented by the symbol γ (alternatively σ or T), is measured in force per unit length. Its SI unit is newton per meter but the cgs unit of dyne per centimeter is also used. For example, Definition Surface tension can be defined in terms of force or energy. In terms of force Surface … See more 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 … See more Thermodynamic theories of surface tension J.W. Gibbs developed the thermodynamic theory of capillarity based on the idea of surfaces of … See more Data table Surface tension of water The surface tension of pure liquid water in contact with its vapor has been given by IAPWS as where both T and the critical temperature TC = 647.096 K are … See more Due to the cohesive forces, a molecule located away from the surface is pulled equally in every direction by neighbouring liquid molecules, … See more Water Several effects of surface tension can be seen with ordinary water: 1. Beading of rain water on a waxy surface, such as a leaf. Water adheres weakly to wax and strongly to itself, so water clusters into drops. … See more Because surface tension manifests itself in various effects, it offers a number of paths to its measurement. Which method is optimal depends upon the nature of the liquid being measured, the conditions under which its tension is to be measured, and the stability of … See more • Anti-fog • Capillary wave — short waves on a water surface, governed by surface tension and inertia • Cheerio effect — the tendency for small wettable floating objects to attract one another.
