Question

Select all that apply.

Pick the TWO true statements from the following:

Graduated cylinders are used to measure volume.

All graduated cylinders measure liquids with the same precision.

Graduated cylinders are the only instruments used to measure volume in the laboratory.

Always read a graduated cylinder from the bottom of the meniscus

Answer 1

Step-by-step explanation:

A graduated cylinder is an apparatus that is used to measure the volume of a liquid.

So, whenever we perform any experiment with liquids then we need to have a graduated cylinder. This is because a graduated cylinder helps in proper or accurate measurement of a liquid.

While reading the volume of a liquid, we always see the lower meniscus to read the accurate value of its volume.

In a laboratory, it is not only the graduated cylinder with which we can measure the volume because in certain reactions pipette is also used to measure the volume.

Therefore, we can conclude that the TWO true statements from the following are:

• Graduated cylinders are used to measure volume.

• Always read a graduated cylinder from the bottom of the meniscus.

Answer 2

The following statements are correct:
1. Graduated cylinder are used to measure volume.
2. Always read a graduated cylinder from the bottom of the meniscus.
Graduated cylinders are one of the instruments used to measure liquid substances in the laboratory. The most accurate way of reading measuring cylinder is to record the value at the bottom of the meniscus.
