The correct answer is: C. measures pressure by sensing deflection of an evacuated chambers.
An aneroid barometer is a type of barometer that uses an evacuated chamber to measure pressure. The chamber is made of a thin metal that is sensitive to changes in pressure. When the pressure changes, the chamber deflects. This deflection is then converted into a measurement of pressure.
Aneroid barometers are very accurate and reliable. They are also very portable and can be used in a variety of applications.
Option A is incorrect because aneroid barometers are very accurate and reliable.
Option B is incorrect because aneroid barometers can measure a variety of pressures, including atmospheric pressure.
Option C is correct because aneroid barometers measure pressure by sensing deflection of an evacuated chambers.
Option D is incorrect because aneroid barometers cannot be used to measure gas or liquid flow rates.
