Why meniscus is formed in graduated cylinder but not in a beaker?
Answers
Answer:
Why a meniscus occurs
Water molecules are attracted to the molecules in the wall of the glass beaker. And since water molecules like to stick together, when the molecules touching the glass cling to it, other water molecules cling to the molecules touching the glass, forming the meniscus.

Meniscus is formed in graduated cylinder but not in a beaker due to the large area of the beaker.
- Meniscus is the curved shape formed as a result of the attraction of molecules of a liquid with its container.
- In a graduated cylinder, the area is very less, so the molecules of liquid that gets attached with the cylinder glass are close and hence attract other molecules and thus forms a meniscus.
- But in the case of beaker, area is large and thus the molecules that attach to the beaker are farther apart and thus do not attract other molecules and hence meniscus is not formed.
