When a glass capillary tube is dipped at one end in water, water rises in the tube. The gravitational potential energy is thus increased. Is it a violation of conservation of energy?

When a capillary tube is dipped into a liquid the liquid neither rises nor falls in the capillary

When a metal wire elongates by hanging a load on it, the gravitational potential energy is decreased. What does that mean?

A capillary tube is dipped first in cold water and then in hot water. Comment on the capillary rise in the second case.

The lower end of a capillary tube is dipped into water and it is seen that the water rises through 7.5 cm in the capillary. Find the radius of the capilary. Surface tension of water =7.5xx10^-2Nm^-1 . Contact angle between water and glass =0^@. Take g=10ms^-2 .

When you lift a box from the floor and put it one an almirah the ptotential energy of the box increases, but thre is no change in its kinetic energy. Is it a violation of consevation of energy?

When you lift a box from the floor and put it on an almirah the potential energy of the box increases bu there is no change in its kinetic energy. Is it violation of conservation of energy ? Explain. (AS_(7))

When the separation between two charges is increased, the electric potential energy of the charges

In a capillary tube, water rises to 3 mm. The height of water that will rise in another capillary tube having one-third radius of the first is:

In a capillary tube experiment, a vertical, 30 cm long capillary tube is dipped in water, the water rises upto a height of 10 cm due to capillary action if this experiment is conducted in a freely falling elevator , the length of the water exists
