Observe the figure and answer the question provided below the figure.

Why does tube B show higher water rise than A?

Tube B shows higher water rise than tube A because surface area is less in the narrow tube or tube B due to which the surface tension is more in that so the level of rise of water is more in that as well. Surface tension is inversely proportional to the surface area and surface tension arises from strong interactions between water molecules so lesser the space or area, more is the compactness and this results in more surface tension eventually leading to higher water rise in the tube.
