Question

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

Answer 1

We should set our eyes in level of the meniscus to take the reading.

Step-by-step explanation:

Meniscus is curving of liquid surface close to the vessel (here graduating cylinder). This curve is formed due to less cohesive forces between water molecules as compared to adhesive forces between water and glass.

Thus water forms a concave meniscus in a glass vessel.

Do to read volume measurement one should set his/her eyes in level of meniscus only.

Answer 2

Due to the adhesion of liquid molecules to the surrounding of the graduated cylinder of to the glass sides of the laboratory ware, the liquid tends to curve. The proper way of using the graduated cylinder is to read off the volume by leveling your eyes to the lower meniscus.
