Therefore, surface tension is dimensionally represented as M 1 T-2. jyashaswylenka jyashaswylenka Answer: … Thanks for watching. 1 answer. The two are equivalent, but when referring to energy per unit of area, it is common to use the term surface energy, which is a more general term in the sense that it applies also to solids. Air molecules have adhered to the new surfaces and reduced the net inward force thus reducing the surface energy. The … asked Dec 5, 2018 in Physics by alam905 (91.0k points) cbse; class-11 +1 vote. Thus, the surface tension formula is: Surface tension = (surface force)/ (length force acts) The volume of the droplet is the main factor, by which the effecting force is determined. The surface tension is denoted by the Greek letter gamma (γ) and, as indicated by Equation 1, is the magnitude F of the force per unit length over which it acts. asked Feb 26, 2018 in Class XI Physics by nikita74 ( -1,017 points) units and measurements The property of surface tension is revealed, for example, by the ability of some objects to float on the surface of the water, even though they are denser than water.

Note- g= acceleration due to gravity and it's dimension is [LT^-2] The denominator 2 has no dimension . CGS unit of surface tension is dyne/cm. . Or, T = [M 1 L 1 T-2] × [L-1] = M 1 T-2. 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. Answer Tension and surface tension have different dimensional formulas as the tension is measured as force and surface tension is measured as force per unit length. The unit is Nm-1 and dimensional formula is M 1 L 0 T-2. . In dealing with liquids, it is more usual to use the idea of Surface Tension rather than Surface energy, even though they refer to the same dimensional quantity. Sl. It is measured in N/m or dyn/cm. Then F = T x 2l. The unit is Nm-1 and dimensional formula is M 1 L 0 T-2. If is the cause of the soap film has less surface tension with definition, unit & formulas at 's!
