Which instrument measures liquid volume?

Which instrument measures liquid volume?

• A. Graduated Cylinder
• B. Beaker
• C. Stopwatch
• D. Digital Balance

Answer: (A)

Measuring liquid volume relies on an instrument with fine, evenly spaced markings that show exactly how much liquid is present. A graduated cylinder is designed for this purpose. It has many precise volume markings along its tall, narrow body, allowing you to read the liquid level in milliliters and to determine the value by looking at the bottom of the meniscus—the curved surface of the liquid. For accuracy, read at eye level. A beaker can hold liquids and often has volume marks, but its broader shape and larger, fewer marks make it less precise for exact measurements. A stopwatch measures time, not volume, and a digital balance measures mass. Therefore, the graduated cylinder is the best tool for measuring liquid volume.
