Question

The diagram shows liquid in a burette and in a measuring cylinder.
Which row shows the readings for the burette and the measuring cylinder?

• A. Burette - $27.8$, measuring cylinder - $42$
• B. Burette - $27.8$, measuring cylinder - $44$
• C. Burette - $28.2$, measuring cylinder - $42$
• D. Burette - $28.2$, measuring cylinder - $44$

Answer 1

Answer: (B)

Burette - $27.8$, measuring cylinder - $44$

A measuring cylinder or mixing cylinder is a common piece of laboratory equipment used to measure the volume of a liquid. It has a narrow cylindrical shape. Each marked line on the measuring cylinder represents the amount of liquid. It is also known as a graduated cylinder.

$\text{Each count = 2 unit. Gives the value of 44.}$

The burette is used to measure the volume of a dispensed substance but is different from a measuring cylinder as its graduations measure from top to bottom. Therefore, the difference between the starting and the final volume is equal to the amount dispensed.

$\text{Each count= 0.1 unit. Gives the value of 27.8}$
