A graphic record of vapor pressure from a flammable/combustible liquid
B graphic record of combustible gases measured in an atmosphere
C charted record of atmospheric temperature over time
D charted record of atmospheric pressure over time
AI Explanation

The correct answer is D) charted record of atmospheric pressure over time. A microbarograph is a precision instrument that provides a continuous graphic record or chart of atmospheric pressure over time. This allows for the monitoring and analysis of changes in barometric pressure, which is an important factor in weather forecasting and maritime navigation. The other answer choices are incorrect because they do not accurately describe the function of a microbarograph. A microbarograph does not provide a graphic record of vapor pressure, combustible gases, or atmospheric temperature.
