Final answer:
Liquid volume can be measured using a graduated cylinder or a burette, and the specific density of liquids can be assessed with a hydrometer. Accurate readings are taken at the bottom of the meniscus.
Step-by-step explanation:
The instrument used to measure liquid volume is a graduated cylinder, which comes in various sizes and is commonly used in laboratory settings. It allows for precise measurements of volumes by sub-dividing the space between milliliter marks. Another instrument used in chemistry for measuring liquid volume is the burette, especially when conducting titrations. Furthermore, a hydrometer can be employed to measure the specific density of liquids, which indirectly helps infer volume based on known densities.
To obtain accurate volume measurements with a graduated cylinder, one should read the volume at the bottom of the meniscus, which is the lowest point of the curved surface of the liquid. It's also essential to ensure that the graduated cylinder is level and that the observer's eye is at the level of the meniscus while making the reading.
