Which instrument is described as a slender, calibrated tube used to measure the volume or transfer a particular quantity of liquid from one container to another?

• A. Graduated Cylinder
• B. Volumetric Flask
• C. A slender, calibrated tube used to measure the volume or transfer a particular quantity of liquid from one container to another
• D. Funnel

Answer: (C)

This describes a pipette. A pipette is a slender, calibrated tube used to measure and transfer a precise volume of liquid from one container to another. The calibration marks on the tube allow you to deliver a known amount, which is essential for accurate measurements in experiments.

This differs from a graduated cylinder, which is wider and mainly used for rough to moderate volume measurements; a volumetric flask, designed for preparing solutions to a exact final volume with a single calibration mark; and a funnel, which simply guides liquid into a container and isn’t used for measuring volumes.
