Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which item measures more precisely?
A
test tube
B
beaker
C
graduated cylinder
D
None of the above
Explanation: 

Detailed explanation-1: -Graduated cylinders are more exact and precise than laboratory flasks and beakers, but they should not be used for volumetric analysis. Instead, utilise volumetric glassware, such as a volumetric flask or volumetric pipette, which is even more accurate and precise.

Detailed explanation-2: -The volumetric flask is the most accurate, but it only measures 1 volume-in this case, 100mL. If you need to measure other volumes besides those on volumetric flasks, then the graduated cylinder is the best tool. The beaker is pretty accurate, and you can easily stir and heat chemicals in it.

Detailed explanation-3: -When measuring liquids in the laboratory, the graduated cylinder provides a more accurate option over beakers and flasks.
