The pressure-sensitive element of an aneroid barometer is called a _______________.

A column of mercury
B pressure bellows
C sylphon cell
D constant pressure capsule
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.
