Question

a meniscus is the curve that forms at the surface of a liquid. true false

Explanation:

A meniscus is indeed the curve that forms at the surface of a liquid. This is due to the forces of adhesion (between the liquid and the container) and cohesion (within the liquid). For example, in water, the meniscus is concave because water molecules are more attracted to the glass container than to each other. In mercury, the meniscus is convex as mercury molecules have stronger cohesion than adhesion to glass.

True
