List of top Chemistry Questions on Surface Tension asked in AP EAPCET

Surface tension of liquids is:

If a water drop of radius 2 cm breaks into \(10^9\) drops of equal size, the work done is about:
(Surface tension of water is \(72 \times 10^{-3}\) N/m)

Consider a circular ring of radius \(1.4\,\text{cm}\) lying on the surface of a liquid. If a vertical force of \(0.022\,\text{N}\) greater than the weight of the ring is required to lift this ring from the liquid surface, then the surface tension of the liquid is
