Final answer:
To find the volume of liquid in the graduated cylinder, read the level at the bottom of the meniscus. For the given example, the volume is estimated between 19.8 mL and 20 mL, and can be reported as approximately 19.9 mL considering visual assessment and potential measurement uncertainties.
Step-by-step explanation:
To measure the volume of liquid in a graduated cylinder, you should make a reading at the bottom of the meniscus, which is the lowest point on the curved surface of the liquid. According to the references provided, the amount of liquid in the graduated cylinder lies somewhere between 19 and 20 milliliters (mL). By examining where the bottom of the meniscus lies on the marked subdivisions, which represent tenths of a milliliter, you can determine a more precise volume. The amount of water is estimated to be between 19.8 mL and 20 mL.
Taking into consideration the curve of the meniscus and its closeness to graduation marks, the measured amount of liquid could be around 19.9 mL, which suggests the volume is less than 20 mL but more than 19.8 mL. However, due to the uncertainty of estimations and the potential for inaccuracy in the cylinder's marks, it's crucial to note that the last digit is an estimate rather than an exact measurement. The graduated cylinder may have minor distortions in its markings, which could affect the precision of the measurement.
Graduated cylinders come in various sizes and are commonly used in laboratories to measure liquid volumes. The scales on these cylinders generally allow for measurements to be taken to the nearest 0.1 mL when they are marked with 1-mL divisions, as is the case with the cylinder in question. For instance, if the meniscus lies between the 21 and 22 mL marks and appears closer to 22, some people might estimate the volume at 21.6 mL or 21.7 mL depending on the visual assessment. It's important to note that it would not be accurate to estimate beyond the tenth-place digit since that digit itself is uncertain.
