Surface Tension

Written by Jerry Ratzlaff. Posted in Properties

Surface tension is the energy or force at the surface of a liquid that holds it together.

formula

\(\sigma = \frac {F} {l}   \)

Where:

\(\sigma\) (Greek symbol sigma) = surface tension

\(F\) = force per unit length

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