Property of fluid by which its own molecules are attracted is called 

Attractive forces of cell walls for water molecules is termed as

A piece of ice. With a stone frozen inside it, is floating in water contained in a beak. When the ice metls,the level of water in the beaker.

The surface tension and vapour pressure of water at $20^oC$ is 7.28$ \times10^{ -2 }$ N/m and $2.33 \times { 10 }^{ 3 }$ pa, respectively. What is the radius of the smallest spherical water droplet which can from without evaporating at $20^oC$ ?

Soldering of two metals is possible because of the property of:

 Work done in increasing the size of a soap bubble from a radius of $3\ cm$ to $5\ cm$ is nearly (Surface tension of soap solution$=0.03\ {Nm}^{-1}$):

If the resultant adhensive force between liquid and solid is smaller than the resultant cohesive then will_______

The dimension of sphere of influence of an molecules is

Ball pen and fountain pen depend respectively upon the principle of

If $2$ bubble of radius $r _1$ & $r _2$ are combined then find radius of common surface.
