Answer Posted / bejoy
capillarity is the rise or fall of a liquid inside a
tubular(open) structure thts placed on the surface of a
liquid... the amount of rise or fall depends on many
factors..if it rises or falls is dependent on the angle of
contact of the liquid with the material of the tube..this is
actuallya term thts dependednt on whether adhesive forces or
cohesive forces dominate at the given interface..it is
physically the angle of the meniscus made by the liquid with
the tube..for water,with glass,it has an acute angle..
u just refer any XI physics text u will get the equations
regaring this..its basicaly just balancing all the
forces..surface tension,weight..etc etc.. a term cos alpha
comes..where alpha is the angle of contact..
