Q

Which instrument is designed to maintain a continuous record of atmospheric pressure?

🔍 Key Concepts

• Difference between instruments that measure instantaneous pressure vs those that make a time record/trace • What the suffix -graph usually means in instrument names • Which instruments in the list are specifically associated with atmospheric pressure rather than temperature

💭 Think About

• Ask yourself: which of these devices not only measures pressure, but also makes a continuous written or drawn record over time? • Look at each choice and decide: does it give a single reading at one moment, or does it record changes automatically on a chart or drum? • Focus on the root words: which name suggests writing or drawing a graph of the pressure?

✅ Before You Answer

• Eliminate any instrument that measures temperature instead of pressure • Identify which options are pressure-measuring devices only and which one is a recording device • Confirm which instrument uses a chart, pen, or stylus to track pressure changes over time
