Question

water, when poured into a thin tube, has a ____ (concave/convex) meniscus​

Answer 1

Answer:

water, when poured into a thin tube, has a _concave__ (concave/convex) mmeniscus

Explanation:

When liquid water is confined in a tube, its surface (meniscus) has a concave shape because water wets the surface and creeps up the side.

But when liquid mercury is confined in a tube, its surface (meniscus) has a convex shape because the cohesive forces in liquid mercury tend to draw it into a drop.

Answer 2

Answer:

concave meniscus
