Define surface tension.. Give units and dimensions.

Explanation

Surface tension
It is a property of liquid by virtue of which the liquid surface tends to occupy a minimum surf area and behaves like a stretched membrane.
It is expressed as force (F) per unit length() i.e. `S=(F)/(l)`
SI, unit of surface tension is `Nm^(-1)`.
Dimensional formula `=[ML^(0)T^(-2)]`
