Select the correct answer.
Which quantity is a graduated cylinder designed for measuring?
A. length
B. mass
C. temperature
D. time
E. volume
Answer (2)
A graduated cylinder is designed for measuring the volume of liquids.
It is not used for measuring length, mass, temperature, or time.
The graduations on the cylinder indicate specific volumes.
Therefore, the correct answer is volume: E .
Explanation
Purpose of a Graduated Cylinder A graduated cylinder is a laboratory apparatus used for measuring the volume of a liquid. It is a tall, cylindrical container with a series of horizontal lines (graduations) marked along its side to indicate specific volumes.
Evaluating the Options Let's consider each option:
A. length: Graduated cylinders are not designed to measure length. Length is typically measured with rulers, calipers, or measuring tapes.
B. mass: Graduated cylinders are not designed to measure mass. Mass is measured using balances.
C. temperature: Graduated cylinders are not designed to measure temperature. Temperature is measured using thermometers.
D. time: Graduated cylinders are not designed to measure time. Time is measured using clocks or timers.
E. volume: Graduated cylinders are specifically designed to measure the volume of liquids.
Conclusion Therefore, the correct answer is E. volume .
Examples
In a chemistry lab, a graduated cylinder is used to accurately measure the amount of liquid needed for an experiment. For example, if a reaction requires 25 mL of hydrochloric acid, a chemist would use a graduated cylinder to measure out that specific volume to ensure the experiment's accuracy. This is crucial in fields like pharmaceuticals, where precise measurements are essential for drug formulation and testing.
A graduated cylinder is specifically designed for measuring the volume of liquids, making option E the correct choice. It features graduations along its side for precise volume readings. This instrument is fundamental in laboratory settings for conducting accurate experiments.
