The following glasswares are used to measure the volume of liquids EXCEPT

Analyze the question: We need the one piece of glassware that is NOT used to measure the volume of liquids.

Explain the concept: In the lab, volume-measuring glassware has graduations (calibrated markings) or a fixed calibration mark:

• Graduated beaker: has approximate volume markings on its side, so it gives rough volume measurements.
• Pipette: delivers a fixed, accurate volume (e.g. 20 cm³ or 25 cm³) of liquid.
• Burette: delivers variable, accurate volumes and is used in titration.
• Test tube: used to hold small samples, heat substances, or carry out simple reactions. It has no calibration markings, so it is not used for measuring volume.

Solution:

1. Check each option for its function in measuring volume.
2. A (graduated beaker), B (pipette), and D (burette) are all calibrated for measuring volume.
3. C (test tube) is only a reaction or holding container, with no scale.

Tip: Ask yourself, "Does it have markings or a calibration line?" If it doesn't, it's a container, not a measuring instrument. For accuracy, remember this order: burette and pipette (most accurate), then measuring cylinder, then graduated beaker (least accurate).
