A _____ is used when it is difficult to measure liquids in a cylindrical or conical graduates, usually for small volumes.

• A. Beaker
• B. Medicine dropper
• C. Pipette
• D. Syringe

Answer: (B)

When you need to add very small amounts of liquid and reading a graduation isn’t feasible, use a tool that delivers liquid in tiny, easily controlled increments. A medicine dropper is designed for that purpose: it releases liquid in drops, allowing dosing or transferring small volumes without relying on calibrated marks. This makes it the best fit for situations where precise reading from a cylinder or conical graduate would be difficult. If exact volume were required, a pipette would be the choice, while a beaker is suited for larger, ungraduated quantities and a syringe is used for drawing or injecting measured amounts.
