The pressure-sensitive element of an aneroid barometer is called a _______________.
AI Explanation
The correct answer is C) sylphon cell.
The pressure-sensitive element of an aneroid barometer is called a sylphon cell. A sylphon cell is a sealed, pressure-sensitive metal bellows that expands and contracts in response to changes in atmospheric pressure. This movement is then translated into a reading on the barometer's display.
The other answer choices are incorrect because:
A) A column of mercury is used in a mercury barometer, not an aneroid barometer.
B) A pressure bellows is a different type of pressure-sensitive element, not specifically used in an aneroid barometer.
D) A constant pressure capsule is also not the pressure-sensitive element in an aneroid barometer.
