Which instrument is used to measure volume?

• A. Graduated cylinder
• B. Pipet
• C. Thermometer
• D. Triple beam scale

Answer: (A)

Volume is the amount of space a liquid occupies, and the tool designed to measure it in most lab settings is the graduated cylinder. It’s built with marked graduations along its side so you can read the volume accurately, typically in milliliters, by looking at the bottom of the meniscus at eye level. The other tools serve different purposes: a pipet is mainly for delivering a precise volume rather than determining an unknown one, a thermometer measures temperature, and a triple beam scale measures mass. So, for measuring how much liquid is present, the graduated cylinder is the best choice.
