(a) Imagine a capillary tube placed in a nonwetting liquid (as opposed to the wetting-liquid situation of Figure 18.35). How does the pressure at a point \(\mathrm{P}\) just below the now convex surface compare with atmospheric pressure?

(b) How does the level in the tube compare with the level of the liquid outside the tube?

Data from Figure 18.35

Curvature means pressure drops across surface, so Pp
