List of top Physics Questions on Surface Tension asked in MHT CET

Two small drops of mercury, each of radius $R$, coalesce to form a single large drop. The ratio of the total surface energies before and after the change is

A light metal disc of radius ' \(r\) ' floats on water surface and bends the surface downwards along the perimeter making an angle ' \(\theta\) ' with the vertical edge of the disc. If the weight of water displaced by the disc is ' W ', the weight of the metal disc is [ \(\text{T}\) = surface tension of water]

Work done to get ' \(n\) ' spherical drops of equal size from a single spherical drop of water, is proportional to

With an increase in temperature, surface tension of liquid (except molten copper and cadmium)

On the surface of the liquid in equilibrium, molecules of the liquid possess

Two drops of equal radius coalesce to form a bigger drop. What is ratio of surface energy of bigger drop to smaller one ?

What is the energy required to increase the radius of a soap bubble from \( R \) to \( 2R \) considering the surface tension \( T \)?
