19. A capillary tube with a radius of 0.0500 cm is in contact with the liquid surface with a surface tension of 72.0 mN/m. What is the minimum overpressure required to blow out an air bubble with a radius equal to that of the capillary? Take the depth of immersion of the capillary in the liquid is negligible.
