tube are greater than the cohesive forces within the liquid
(A) the liquid level in a capillary tube will rise above the surrounding
liquid and the surface in the capillary tube will have a convex meniscus
(B) the liquid level in a capillary tube will rise above the surrounding
liquid and the surface in the capillary tube will have a concave meniscus
(C) the liquid level in a capillary tube will drop below the surrounding
liquid and the surface in the capillary tube will have a convex meniscus
(D) the liquid level in a capillary tube will drop below the surrounding
liquid and the surface in the capillary tube will have a concave meniscus
