Au-shaped tube is open at both ends (see figure next page). the tube initially has some water in . an amount of a second liquid, which is immiscible with water, is poured into one arm of the tube. once the arrangement comes to equilibrium, the top of the water in the tube stands 16.6 cm above the interface between that liquid and the water (which is at level a in the diagram). the top of the water column in the other arm is 3.32 cm above
