1. A 3-mm diameter tube is inserted in mercury and in water. a. Assuming the tube is clean so that the angle of contact with mercury is 140 degrees and the surface tension is 0.5140 N/m, what is the amount of depression? b. What is the amount of rise of water inside the tube assuming an angle of contact of 0 degree and a surface tension of 0.0728 N/m? c. If the tube is replaced by two parallel, wide, clean glass plates separated by a distance of 2mm, how far does the water rise due to capillary action assuming surface tension amounting to 0.0730 N/m.
