What is the correct method for reading the volume of a graduated cylinder?

Reading the volume of a graduated cylinder requires attention to the meniscus, which is the curve that occurs at the surface of a liquid in response to the walls of the container. The correct method is to read from the bottom of the meniscus. This is crucial because the surface tension of the liquid causes it to curve slightly, and the bottom of the meniscus represents the true measurement of the liquid's volume.

If you were to read from the top of the liquid line, it could lead to inaccuracies, as this point does not reflect the actual volume. Reading from the markings without considering the meniscus would also result in errors. Additionally, estimating based on markings can introduce subjectivity and further inaccuracies. Therefore, reading from the bottom of the meniscus ensures that measurements are as precise and reliable as possible.
