An instrument designed to maintain a continuous record of atmospheric pressure is a(n) _______________.
AI Explanation
The correct answer is A) barograph.
A barograph is an instrument designed to maintain a continuous record of atmospheric pressure over time. It uses a pressure-sensitive aneroid cell to track changes in pressure and records this data on a graph or chart, providing a visual representation of the pressure trends. This makes the barograph the most appropriate instrument for continuously monitoring and recording atmospheric pressure data.
The other options are incorrect because:
B) An aneroid barometer measures atmospheric pressure but does not record it continuously.
C) A thermograph records temperature, not atmospheric pressure.
D) A mercurial barometer measures atmospheric pressure using a column of mercury, but does not provide a continuous record.
