Graduated Cylinders

Front

What is a graduated cylinder?

Back

A graduated cylinder is a piece of laboratory equipment used to measure the volume of a liquid accurately.

Front

How do you read the measurement on a graduated cylinder?

Back

To read a graduated cylinder, look at the bottom of the meniscus (the curve of the liquid) at eye level to determine the volume.

Front

What is the meniscus?

Back

The meniscus is the curve seen at the surface of a liquid in response to its container, often used in measuring liquid volumes.

Front

What is the purpose of the markings on a graduated cylinder?

Back

The markings on a graduated cylinder indicate the volume of liquid contained within, allowing for precise measurements.

Front

What is the smallest increment typically found on a graduated cylinder?

Back

The smallest increment can vary, but common graduated cylinders have increments of 1 mL or 0.1 mL.

Front

How do you determine the volume of liquid in a graduated cylinder?

Back

You determine the volume by reading the measurement at the bottom of the meniscus.

Front

What is the difference between a graduated cylinder and a beaker?

Back

A graduated cylinder is designed for precise volume measurements, while a beaker is used for mixing and holding liquids.

Front

What is the volume of liquid if the meniscus is at the 20 mL mark?

Back

The volume of the liquid is 20 mL.

Front

If a graduated cylinder shows a reading of 15.5 mL, what does this mean?

Back

It means that the volume of liquid in the graduated cylinder is 15.5 mL.

Front

Why is it important to read the graduated cylinder at eye level?

Back

Reading at eye level helps avoid parallax error, which can lead to inaccurate measurements.
