Which instrument is used for measuring the volume of liquids?

• A. Graduated cylinder
• B. Beaker
• C. Volumetric Flask
• D. Pipette

Answer: (A)

Measuring liquids with marked accuracy is best done with a graduated cylinder. It’s specifically designed with calibrated markings that let you read the exact volume by looking at the bottom of the meniscus, usually at eye level, giving a reliable balance between ease of use and precision for common lab volumes.

A beaker provides rough measurements with wide increments and is not intended for precise volume readings. A volumetric flask is calibrated to contain an exact volume when filled to a mark, but it’s meant for preparing solutions to a precise final volume rather than measuring arbitrary liquid volumes. A pipette is used to transfer a specific volume with high precision, not to measure the volume of a liquid in a general sense.

So, for measuring liquids, the graduated cylinder is the most appropriate tool.
