Question

Which statement correctly describes measuring with a graduated cylinder?

The liquid in the cylinder usually forms a convex meniscus.
Measurement is taken at the bottom of the meniscus.
Measurement is taken at the top of the meniscus.
The liquid in the cylinder can only be water.

Answer 1

measurement is taken at the bottom of the meniscus.

Answer 2

measurement is taken at the bottom of the meniscus.

Step-by-step explanation:

the first answer is not correct since water forms a convex meniscus while Mercury forms cone meniscus just as indicated in the photographs above.

I agree with the second point since we were taught that the Reading should always be taken at the bottom of the meniscus.not on top of the meniscus.

the liquid in the cylinder cannot only be water. we can either put water, Mercury or any other liquid,but not specifically water.
