137. On what does the operation of an aneroid barometer depend?
An aneroid barometer functions through the flexing of a thin, metal, airtight cell. This instrument does not rely on liquids like mercury or alcohol, distinguishing it from other types of barometers. The cell's expansion and contraction, due to changes in atmospheric pressure, are mechanically linked to a pressure indicator.
