Question

To measure out a volume of liquid, start by choosing the appropriate graduated cylinder and moving the bumper to the of the graduated cylinder to protect it from breakage. Then, pour the liquid into the graduated cylinder until the of the meniscus aligns with the desired volume marking when you look at the graduated cylinder from

Answer 1

Answer:

Eyes are placed directly at the level of the lower meniscus

Explanation:

A graduated cylinder (also referred to as measuring cylinder) is a laboratory equipment, usually made of glass, used to measure the volume of liquids in the laboratory. It is of different sizes and precision; the desired volume determines the size one uses.

When measuring the volume of a liquid, the lower meniscus of the liquid poured into the graduated cylinder is measured and the eyes are placed directly at the level of this lower meniscus.

NOTE: This same rule/pattern applies to determining the measurement of all calibrated glasswares in the laboratory.
