What instrument is used to measure volume?

The graduated cylinder is the appropriate instrument for measuring volume because it is specifically designed for this purpose. This cylindrical container typically has marked lines that indicate different volume levels, allowing for precise measurement of liquids. The shape of the graduated cylinder helps to minimize errors in reading the volume, as it provides a clear view of the liquid level against the graduated markings.

In laboratory settings, accuracy in volume measurement is crucial for experiments and chemical reactions. Graduated cylinders come in various sizes, each with a scale that helps to achieve the exact volume needed for various applications, from simple measurements to more complex tasks in scientific research.

In contrast, a thermometer is used for measuring temperature, a barometer measures atmospheric pressure, and a pipette is typically employed for transferring small volumes of liquids, not for general measurement. Each of these tools serves a unique purpose within scientific contexts, which highlights the specialized function of the graduated cylinder in volume measurement.
