Paper Details

A capillary rise experiment is proposed for a high school physics class. The students are told that for water in clean glass tubes, the contact angle between liquid and glass (0) is 90°. The students are asked to measure capillary rise in a series of tube diameters (D = 0.05 cm, 0.10 cm, 0.15 cm, 0.20 cm, etc.). They are then asked to graph the results and determine the approximate tube diameters that would produce capillary rises of 3 cm, 2 cm, and l cm. Predict the results if the water used in the experiment is 20°C.
