Which of the following sets of laboratory tools should be used to record the most complete data about a gas sample during an experiment?

• A. Beaker, ruler, and stopwatch
• B. Barometer, thermometer, and gas syringe
• C. Pipette, funnel, and filter paper
• D. Bunsen burner, crucible, and tongs

Answer: (B)

Verified step by step guidance

1. Step 1: Identify the key properties of a gas sample that need to be measured to record complete data. These typically include pressure, temperature, and volume.
2. Step 2: Understand which laboratory tools measure these properties: a barometer measures pressure, a thermometer measures temperature, and a gas syringe measures volume.
3. Step 3: Evaluate the options given: Beaker, ruler, and stopwatch do not measure pressure or temperature; pipette, funnel, and filter paper are used for liquids and solids, not gases; Bunsen burner, crucible, and tongs are for heating and handling materials, not measuring gas properties.
4. Step 4: Conclude that the set containing barometer, thermometer, and gas syringe is the most appropriate because it allows measurement of all critical gas properties (pressure, temperature, and volume) for complete data recording.
5. Step 5: Remember that accurate data collection in gas experiments requires tools that directly measure the physical parameters of gases, ensuring reliable and comprehensive results.
