Nutrient dissolved in water are earned to upper parts of plants by tiny tubes partly because of the capillary effect. determine how high the water solution will rise in tree in a 0.005-mm-diameter tube as a result of the capillary effect. treat the solution as water at 20 degree c with a contact angle of 15 degree.
