Question

Define surface tension and derive expression for it?​

Answer 1

Answer:

Surface tension is defined as, The ratio of the surface force F to the length L along which the force acts. Mathematically, surface tension can be expressed as follows: T=F/L.

Answer 2

According to the definition of surface tension, it is the phenomenon that occurs when the surface of a liquid is in contact with another phase (it can be a liquid as well). Liquids tend to acquire the least surface area possible. The surface of the liquid behaves like an elastic sheet.

“Surface tension is the tension of the surface film of a liquid caused by the attraction of the particles in the surface layer by the bulk of the liquid, which tends to minimise surface area”.

To derive a formula means to deduce, obtain, or prove the formula from a set of already-known or already-established principles or observations. ... Then, you work from the accepted laws and theories, using math and logic, to derive whatever formula you are trying to derive.
