On what does the operation of an aneroid barometer depend?

🔍 Key Concepts

• Difference between mercurial barometer and aneroid barometer • How atmospheric pressure can act on a sealed or nearly sealed device • What kinds of liquids or metals are used in different barometer types

💭 Think About

• First, which choices clearly describe instruments that use a liquid column rather than a mechanical element? Eliminate those for aneroid. • Think about the word "aneroid" (meaning "without liquid"): which option fits a barometer that does NOT use liquid at all? • Which component could flex or deform when outside air pressure changes, allowing a pointer to move over a scale?

✅ Before You Answer

• Identify which options involve mercury or alcohol (these are NOT features of an aneroid barometer). • Focus on which option describes a sealed metal device whose shape can change with pressure. • Make sure your final choice matches the idea of a barometer operating without any liquid column.
