Proteinuria, excess protein in the urine, is a symptom of many kidney diseases. A marker for proteinuria is a decrease in the surface tension of a urine sample over the course of a few hours, typically from 31 mN/m to 29 mN/m; the surface tension of normal urine does not change with time. The change in surface tension can be measured by monitoring the height of the liquid in a capillary tube. ? Part A For a patient who has proteinuria, how high in mm will the liquid initially rise in a 0.80-mm-diameter capillary tube? You can assume that the density of urine is the same as that of water.
