A graduated cylinder is filled with   cm  of liquid. The liquid is poured into a different cylinder that has a radius of   cm.What will the height of the liquid be in the new cylinder?

Define surface tension and explain how it is responsible for the phenomenon of capillarity. A glass tube with an inner radius of 0.5 mm is dipped into water. The water level inside the tube is observed to rise to a height of 20 mm above the external water level. Calculate the surface tension of water.
