Surface Tension

Surface tension, abbreviated as \( \sigma \) (Greek symbol sigma), is the energy or force at the surface of a liquid that holds it together.

Surface Tension formula

\(\large{ \sigma = \frac {F} {l}   }\)

Where:

\(\large{ \sigma }\)  (Greek symbol sigma) = surface tension

\(\large{ F }\) = force per unit length

\(\large{ l }\) = length of a surface ares that keep sliding side stationary
