Reading 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

What is the purpose of the meniscus in a graduated cylinder?

Back

The meniscus is the curve at the surface of a liquid in a graduated cylinder, and it is important to read the volume at the bottom of this curve for accuracy.

Front

How do you read the volume in a graduated cylinder?

Back

You read the volume at the bottom of the meniscus, ensuring your eye is level with the liquid.

Front

What is the unit of measurement for volume in a graduated cylinder?

Back

The unit of measurement for volume in a graduated cylinder is milliliters (mL).

Front

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

Back

A beaker is used for mixing and holding liquids, while a graduated cylinder is specifically designed for measuring the volume of liquids accurately.

Front

What is the significance 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 volume of a liquid if the meniscus is at the 250.0 mL mark?

Back

The volume of the liquid is 250.0 mL.

Front

Why is it important to avoid parallax error when reading a graduated cylinder?

Back

Parallax error occurs when the measurement is read from an angle rather than straight on, leading to inaccurate volume readings.

Front

What is the volume of a liquid if it is measured at the 60.0 mL mark?

Back

The volume of the liquid is 60.0 mL.

Front

What should you do if the liquid level is between two markings on the graduated cylinder?

Back

If the liquid level is between two markings, estimate the volume to the nearest tenth of a milliliter.
