Surface tension is the elastic tendency of fluid surfaces that lets insects to float on water. Learn the surface tension of water and the formula to find the surface tension of the given liquid @BYJU’S.
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.
The surface tension is force per length and is measured by [N/m] and is acting to stretch the surface. Surface tension results from a sharp change in the density between two adjoined phases or materials. There is a common misconception for the source of the surface tension.
24 wrz 2024 · surface tension, property of a liquid surface displayed by its acting as if it were a stretched elastic membrane. This phenomenon can be observed in the nearly spherical shape of small drops of liquids and of soap bubbles.
Surface tension is a direct measure of this energy loss per unit area of surface. If the characteristic molecular dimension is R and its area thus R 2 , then the surface tension is σ ∼ U/(2R 2 ).
Surface energy is necessarily accompanied by surface forces, because work has to performed if the area of an interface and thus its surface energy is increased. The surface energy per unit of area or equivalently the force per unit of length is called surface tension.
Surface Tension. Cohesive forces between molecules cause the surface of a liquid to contract to the smallest possible surface area. This general effect is called surface tension. Making Connections: Surface Tension. Forces between atoms and molecules underlie the macroscopic effect called surface tension.
