A glass capillary tube of internal diameter 0.6 mm is held vertically with the lower end in water and with 80 mm of the tube above the surface of water. How much high does the water rise? If the tube is now lowered unitil 30 mm of its length is above the surface of water, what happens? Surface tension of water is 75 dyne/cm and g = 1000 cm/s^2
