Answer:
D. it changes sound waves into electric impulses.
Explanation:
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
I would say extreme temperatures.
D. The fact paper bags tear easily and fall apart when wet is a limitation (cost) of using them, while the other options are pros.
