In case of plants nutrients & water pass through capillary tube of radius `2.5xx 10^-5 m`. Surface tension of the water ` T = 7.28 xx10^-2 N//m` & angle of contact is `0^@`. Is surface tension enough to supply water to the top?

A liquid of density 830 kg. m^-3 rises through 0.0893 m in a capillary tube of diameter 1.68xx10^-4 m. Determine the surface tension of the liquid. Take the angle of contact as 0^@ .

If the surface tension of water is 7.3xx10^-2 N. m^-1 , then what is the pressure inside a spherical drop of water of radius 10^-3 m?

What is the excess pressure inside a spherical soap bubble of radius 5 cm if the surface tension of the soap film is 3.5xx10^(-2)Nm^(-1) ?

What will be the work done to form a soap-bubble of radius 5 cm? The surface tension of soap-water = 70 dyn. cm^-1

Determine the surface energy of a soap-water film formed on a frame of area 10^-3m^2 . Surface tension of soap-water =70xx10^-3N.m^-1 .

Find the excess pressure inside a rain water drop of diameter 0.02 cm. The surface tension of water = 0.072 N. m^-1 .

The surface tension T = 7.28 xx 10^-2 N//m and the contact angle is 0^@ for any liquid. The radius of the capillary tube is r = 2.5 xx 10^-5m . Is surface tension sufficient to rise the water?

In a capillary tube water rises up to a certain height and the upward force due to surface tension balances the force of 7.5xx10^-4 N due to weight of water. If the surface tension of water is 6xx10^-2 N. m^-1 then what will be the internal circumference of the capillary tube?
