19 Νοε 2024 · Surface tension is the tendency of a liquid‘s surface to resist external forces, minimizing its surface area and behaving as if it were covered by a stretched elastic sheet. It arises due to the cohesive forces between liquid molecules, particularly at the surface, where molecules experience a net inward pull.. Key Points. Definition: Surface tension is the tendency of a liquid’s surface ...
Thus, the surface tension formula is: Surface tension = (surface force)/ (length force acts) γ = F /d. Over here: Γ refers to the Surface tension. F is the force which applies to the liquid. d refers to the length where the force acts. Solved Examples on Surface Tension
20 Δεκ 2022 · Formula. Surface Tension is given by the ratio of the surface force (F) to the length of the force acting (L). Thus, surface tension formula can be expressed as: T = F/L. where, F – force per unit length L – length of the acting force T – surface tension
2 Μαΐ 2024 · Surface tension is the ratio of the dragging force to the length and thus its SI unit is N/m as force is measured in N and length is measured in m. In the CGS system, its unit is Dyne/cm. The dimension formula of Force is [MLT -2] whereas the dimension of length is [L] thus, the dimensional formula of Surface Tension is [M L 0 T -2].
Here is an example for calculating surface tension by using the formula. Compute the surface tension of a given liquid whose dragging force is 7 N and the length in which the force acts is 2 m? Solution: Given, F = 7 N; L = 2 m; According to the formula, T = F/L . ⇒ T = 7/2. ⇒ T = 3.5 N/m
29 Μαΐ 2024 · Surface tension, denoted by the Greek letter gamma (γ), is quantified as the force per unit length acting along the liquid surface. It is expressed in Newtons per meter (N/m) or dynes per centimeter (dyn/cm). The formula for surface tension is: γ = F/L.
Surface tension is defined as the energy required to increase the surface area of a liquid, or the force required to increase the length of a liquid surface by a given amount. This property results from the cohesive forces between molecules at the surface of a liquid, and it causes the surface of a liquid to behave like a stretched rubber membrane.
