The property of surface tension is obtained in

Describe a simple experiment for the measurement of the surface tension of a liquid.

Why are clothes easily washed by soap or detergent?

$A$ $10\, cm$ long wire is placed horizontally on the surface of water and is gently pulled up with a force of $2 \times 10^{-2}\, N$ to keep the wire in equilibrium. The surface tension,in $N/m$,of water is:

Why does the free surface of a liquid tend to contract?

The surface tension of a liquid is $70 \, dyne/cm$. In $MKS$ system its value is
