Surface Tension...

Oil spreads over the surface of water whereas water does not spread over the surface of the oil, due to

The property utilized in the manufacture of lead shots is

The dimensions of surface tension are

A wooden stick 2 m long is floating on the surface of the water. The surface tension of water is 0.07 N/m. By putting soap solution on one side of the stick, the surface tension is reduced to 0.06 N/m. The net force on the stick due to surface tension will be:

Surface tension may be defined as:

The energy needed to break a drop of radius R into n drops of radii r is given by:

The potential energy of a molecule on the surface of liquid compared to one inside the liquid is  -

Two droplets merge with each other and forms a large droplet. In this process

Work done in splitting a drop of water of 1 mm radius into 10⁶ droplets is (Surface tension of water = 72 × 10^-3 J/m²

The amount of work done in blowing a soap bubble such that its diameter increases from d to D is (T= surface tension of the solution)
