How to Read Graduated Cylinders

How do you read the measurement on a graduated cylinder?

• Look at the top of the liquid meniscus at eye level.

• Read the measurement from the side of the cylinder.

• Look at the bottom of the meniscus at eye level.

• Estimate the measurement based on the nearest mark.

Why is it important to use the correct size graduated cylinder?

• It allows for faster measurements.

• It ensures accurate measurements and reduces the risk of overflow.

• It makes the experiment look more professional.

• It is required by laboratory regulations.

What does 'mL' stand for?

• milliliters

• meters

• moles

• milliunits

What is a graduated cylinder?

• A tool used to measure temperature in a laboratory.

• A laboratory instrument used to measure the volume of a liquid accurately.

• A device for mixing chemicals in a lab.

• A container for storing solid materials.

How can you tell if a graduated cylinder is accurate?

• By checking if it is calibrated and has clear, unbroken markings.

• By ensuring it is made of glass instead of plastic.

• By measuring the weight of the cylinder when empty.

• By looking for a brand name on the cylinder.

What is the smallest division on a graduated cylinder?

• The smallest division is the smallest increment marked on the graduated cylinder, which can vary by the cylinder's size.

• The smallest division is always 1 mL regardless of the cylinder's size.

• The smallest division is the total volume of the graduated cylinder divided by the number of markings.

• The smallest division is the largest increment marked on the graduated cylinder.

How do you measure a liquid that is above the maximum volume of the graduated cylinder?

• You can measure it accurately with a smaller graduated cylinder.

• You cannot measure a liquid above the maximum volume; you need a larger graduated cylinder.

• You can estimate the volume by eyeing it.

• You can pour some out until it is below the maximum volume.

What is the maximum volume a graduated cylinder can measure?

• The maximum volume is indicated by the highest marking on the graduated cylinder.

• The maximum volume is always 1000 mL regardless of the cylinder size.

• The maximum volume is determined by the width of the cylinder.

• The maximum volume is the total capacity of the cylinder without any markings.

What is the meniscus?

• The meniscus is the curve at the surface of a liquid in a graduated cylinder, which is caused by surface tension.

• The meniscus is a type of liquid that does not mix with water.

• The meniscus is a measurement tool used to determine the volume of a solid.

• The meniscus is the solid residue left after a liquid evaporates.

What is parallax error?

• A type of error caused by reading measurements from an angle rather than straight on.

• An error that occurs when the instrument is not calibrated correctly.

• A mistake made when recording data in a spreadsheet.

• An error that happens when the observer's eye is not aligned with the measurement scale.
