Measuring volume in a graduated cylinder

What is the meniscus?

• The meniscus is the curve at the surface of a liquid in a container, such as a graduated cylinder.

• The meniscus is a type of liquid that does not evaporate.

• The meniscus is a measurement of the volume of a solid.

• The meniscus is the temperature at which a liquid boils.

What is the purpose of using a graduated cylinder instead of a beaker?

• A graduated cylinder is easier to clean than a beaker.

• A graduated cylinder provides more accurate volume measurements than a beaker.

• A graduated cylinder is more durable than a beaker.

• A graduated cylinder is less expensive than a beaker.

What does it mean if a graduated cylinder is filled to 10 mL?

• It means that the liquid occupies a volume of 10 milliliters.

• It means that the liquid is at a temperature of 10 degrees Celsius.

• It means that the liquid weighs 10 grams.

• It means that the liquid is 10% full.

What is parallax error?

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

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

• A mistake made when using digital measuring devices.

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

If a graduated cylinder shows 24 mL, what does that indicate?

• It indicates that the liquid in the cylinder occupies a volume of 24 milliliters.

• It indicates that the liquid in the cylinder is at a temperature of 24 degrees Celsius.

• It indicates that the graduated cylinder is 24% full.

• It indicates that the liquid in the cylinder weighs 24 grams.

What is a graduated cylinder?

• A device used to measure temperature in a laboratory.

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

• A tool for mixing chemicals in a lab.

• A container for storing solid materials.

What is displacement in terms of volume measurement?

• Displacement is the method of measuring the volume of an irregularly shaped object by observing how much liquid it pushes out of the way.

• Displacement refers to the total weight of an object when submerged in water.

• Displacement is the process of calculating the area of a flat surface.

• Displacement measures the temperature change of a liquid when an object is added.

Why is it important to read the meniscus at eye level?

• It allows for a more aesthetic view of the liquid.

• Reading at eye level prevents parallax error, which can lead to inaccurate volume measurements.

• It helps in identifying the type of liquid being measured.

• It ensures that the container is clean and free of residues.

How can you tell which object has the greatest volume?

• By measuring the weight of the objects

• By comparing their dimensions

• By measuring how much liquid they displace when submerged

• By observing their shapes

How do you read the volume in a graduated cylinder?

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

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

• Estimate the volume based on the nearest mark.

• Read the volume from the side of the cylinder.
