Question

describe how the meniscus is used to read volume measurements on a graduated cylinder.

Explanation:

When reading volume in a graduated cylinder, view the meniscus at eye - level. For a concave meniscus (common with water), read the bottom of the curve. For a convex meniscus, read the top of the curve. This ensures accurate volume measurement as the meniscus forms due to surface tension and adhesion/cohesion forces between the liquid and the cylinder wall.

Answer:

View the meniscus at eye - level. For a concave meniscus, read the bottom of the curve; for a convex meniscus, read the top of the curve.
