A square framed with a wire of side 'L' is dipped in a liquid. On taking out, a membrane is formed. What will be the force acting on the frame if the surface ' tension of liquid is S?

In what direction does the buoyant force on an object immersed in a liquid act?

Mercury has an angle of contact equal to 140^@ with soda lime glass. A narrow tube of radius 1.00 mm made of this glass is dipped in a trough containing mefcury. By what amount does the mercury dip down in the tube relative to the liquid surface outside? Surface tension of mercury at the temperature of the experiment is 0.465 N m^-1 . Density of mercury = 13.6 xx 10^3 kg m^-3

A U-shaped wire is dipped in a soap solution, and removed. The thin soap film formed between the wire and the light slider supports a weight of 1.5 xx10^-2 N (which includes the small weight of the slider). The length of the slider is 30 cm. What is the surface tension of the film?

Calculate the excess pressure inside a| liquid drop of radious r and surface tension T. What is the expression of I excess presure inside a soap bubble?

What is surface tension of a liquid ? Show that the surface tension of a liquid is numerically equal to the sueface energy per unit area.

Fill in the blanks using the word{s) from the list appended with each statement: Surface tension of liquids generally ………………..with temperatures (increases / decreases)
