MTTC 103 Elementary Practice

The primary function of a graduated cylinder is to measure the volume of liquids accurately. This laboratory instrument is specifically designed with markings along its side that indicate the volume of liquid contained within. The narrow, tall shape of the cylinder allows for precise measurements and minimizes the surface tension effect, making it suitable for measuring various liquids, from water to chemical solvents.

Unlike options related to measuring temperature or determining mass, which require different tools such as thermometers and balances respectively, a graduated cylinder's design and calibration make it ideal for volumetric measurements. Similarly, while analyzing gas composition requires specialized equipment like gas chromatographs, the graduated cylinder's primary role remains focused on quantifying liquid volumes. Therefore, the correct answer highlights the unique function of the graduated cylinder within the context of scientific measurement.
