Barometers are calibrated at a standard temperature of _______________.

A 0°F
B 32°F
C 60°F
D 70°F
AI Explanation

The correct answer is B) 32°F. Barometers are calibrated at a standard temperature of 32°F (0°C) because this is the freezing point of water at standard atmospheric pressure. This standard temperature is specified in regulations and standards related to barometer calibration, as it provides a consistent reference point for accurate pressure measurements. The other options are incorrect because 0°F is too cold, 60°F and 70°F are too warm compared to the standardized 32°F calibration temperature.
