Which instrument is used to measure very small volumes of liquid with precision?

• A. Beaker
• B. Thermometer
• C. Pipette
• D. Burette

Answer: (C)

When you need to measure very small volumes with precision, a pipette is the tool designed for that task. Pipettes are calibrated to deliver exact amounts of liquid, and you can read a precise value from their scales or use a volumetric pipette to dispense one specific volume. This makes them ideal for small-volume work, down to microliters in many cases. Beakers are general containers and don’t provide precise volume measurements. Thermometers measure temperature, not liquid volume. Burettes can deliver precise volumes during titrations, but they are typically used for larger volumes and reading the amount dispensed, not for achieving the smallest-volume measurements with the highest precision.
