In a capillary rise experiment, the height (h) to which a liquid rises depends on the density (d) and surface tension (ɣ) of the liquid and the radius of the capillary (r). The equation relating these quantities and the acceleration due to gravity (g) is h = 2ɣ/dgr. The sketch provides data obtained with ethanol. What is the surface tension of ethanol?
