The end of a capillary tube with a radius `r` is immerseed into water. What ammount of heat will be evolved when the water rises in the tube ? If surface tension of water `'T'` density of water `= rho`. Given `(T^(2))/(rhog) = (2)/(pi)`.

The end of a capillary tube with a radius r is immersed in water. Is mechanical energy conserved when the water rises in the tube? The tube is suficiently long. If not calculate the energy change.

The end of a capillary tube of radius r is immersed in water of surface tension T and density rho . How much heat will be evolved when water rises in the tube? [Hint: Heat evolved = work done by surface tension - gravitational energy stored in the standing column.]

A capillary tube of area of cross-section A is dipped in water veritcally. Calculate the amount of heat evolved as the water rises in the capillary tunbe upto height h. The density of water is rho

If a capillary tube of radius r is immersed in waster of surface tension T and density rho , how much heat will be evolved when capillary rise takes place completely ?

The height of water in a capillary tube of radius 2 cm is 4 cm . What should be the radius of capillary , if the water rises to 8cm in tube ?
