If the adhesive forces between a liquid and the walls of a capillary tube are greater than the cohesive forces within the liquid
olga_2 [115]

Answer:

Option A, 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.

Explanation:

A liquid will wet the surface of the container in which it is contained only when the adhesive forces between the molecules of the liquid are weaker than the adhesive force between the surface wall of the container and water.

A  convex meniscus is formed when the attractive forces between the molecules of liquid (cohesion) becomes greater than attractive forced between the water molecule and the container's surface (adhesion)

Convex meniscus simultaneously move the surface of the liquid in the downward direction due to which its level become lower than the surrounding layer.

Hence, option A is correct

Hoochie [10]

Answer:

The answer is D

Explanation:

Chloroplasts use carbon dioxide and water to make glucose, with oxygen as a byproduct.

The glucose produced is then used in metabolic reactions in the organism.
