What characteristic makes beakers less suitable for precise liquid measurements compared to graduated cylinders?

Beakers are generally wider and have a more open design compared to graduated cylinders, which impacts their precision in measurement. The wide mouth of a beaker allows for easier pouring and mixing, but it also means that the liquid surface is less easily defined at specific measurement points, leading to potential errors when trying to read the volume. Graduated cylinders, on the other hand, are designed specifically for measuring liquids, with a long, narrow shape that allows for a more accurate reading of the liquid meniscus, the curved surface generated by the liquid in the container. This design minimizes any variation caused by width, as the scale markings are closely spaced along the cylinder's height, making it easier to discern the meniscus level accurately.

The other choices present characteristics that do not accurately influence the comparison between beakers and graduated cylinders for liquid measurement. For instance, beakers can come in a range of volume capacities and can certainly measure liquids and not just solids, nor is there a general quality issue with material durability compared to graduated cylinders.
