What does a graduated cylinder typically measure?

A graduated cylinder is specifically designed for measuring the volume of liquids. Its cylindrical shape allows for precise readings and the marked graduations along its length provide a scale for measurement. When a liquid is poured into the graduated cylinder, the meniscus—where the liquid's surface curves due to surface tension—is read at eye level to ensure accuracy. This makes graduated cylinders an essential tool in laboratories and various scientific fields where knowing the exact volume of liquids is crucial.

Other options, such as measuring mass, temperature, or gas pressure, require different types of instruments. Mass is typically measured using a balance or scale, temperature is measured with a thermometer, and pressure is gauged using a manometer or pressure gauge. Each of these instruments is calibrated for its specific purpose, highlighting the distinct role of the graduated cylinder in measuring liquid volumes.
