WebSep 24, 2024 · The surface tension is the force acting perpendicular on a unit length of an imaginary line drawn on the surface of the liquid and it can be expressed as. T=F\l. Here, T is surface tension, F is the force acting on the surface (Cohesive force) and l is unit length. Because of surface tension, few insects can easily float on the liquid surface. WebApr 12, 2024 · Surface tension is expressed in energy (joules) per unit area (square meters). It is often expressed as an amount of force exerted on the surface perpendicular to a line …
WebApr 8, 2024 · The surface tension is present due to the imbalance of attractive intermolecular forces or we say the cohesive forces that are between molecules. This phenomenon mostly occurs with water generally but it can happen with other liquids as well. ... That is written as meter N·s/m 2 also frequently expressed in the equivalent forms. … WebThe energy responsible for the phenomenon of surface tension may be thought of as approximately equivalent to the work or energy required to remove the surface layer of molecules in a unit area. Surface tension may be expressed, therefore, in units of energy ( … newton, absolute unit of force in the International System of Units (SI units), … surface, in chemistry and physics, the outermost layer of a material or …
WebThe surface tension, γ, may be defined as the force/unit length parallel to the surface which is exerted perpendicular to any line drawn in the surface. Surface tension is sensitive to curvature of the surface only for very small radii of curvature (see interfaces). The units of surface tension are mNm −1. WebSep 9, 2024 · We describe the tendency of a surface to contract by drawing an imaginary line in the surface, and we say that the surface to one side of the line pulls the surface of the …
