Question: 1 / 400

When measuring liquid in a graduated cylinder, where does the volume of liquid read?

Top surface of the liquid

Top of the meniscus

Center of the meniscus

Bottom of the meniscus

When measuring liquid in a graduated cylinder, the volume of liquid should be read at the bottom of the meniscus, which is the curved surface of the liquid. This is because the liquid in the cylinder will curve slightly due to surface tension, creating a concave shape and making it appear higher than it actually is. Reading at the bottom of the meniscus eliminates this error and gives the most accurate measurement. The top surface of the liquid, while seemingly the most logical choice, can also lead to incorrect readings as the liquid may cling to the sides of the cylinder. Reading at the top of the meniscus or center of the meniscus may also result in inaccuracies.
