If the coal mine was deep (not a drift mine) it would register higher pressure due to the extra weight or air above it.

What would a barometer reading be if you there was no barometric pressure?

A barometer measures atmospheric pressure, so if there was no barometric pressure, the barometer reading would likely show a value of zero or indicate an error. Atmospheric pressure is necessary for the functioning of a barometer.


How can an aneroid barometer give reading in inches of mercury when it doesn't use any mercury?

Good question.Look at it like this if you had two barometers side by side, one a mercury barometer and the other a barometer that reacted to changes in air pressure using some bellows and a spring.Then, as the pressure changed you marked the second barometer positions and noted on the dial the inches reading from the mercury barometer, the second barometer measurement scale would mimic the real mercury barometer even though it did not actually use any mercury.


How would a barometer reading change with a cold front?

A barometer reading would change with a cold front because the density of mercury will change with temperature, so a reading must be adjusted for the temperature of the instrument. For this purpose a mercury thermometer is usually mounted on the instrument. Temperature compensation of an aneroid barometer is accomplished by including a bi-metal element in the mechanical linkages. Aneroid barometers sold for domestic use typically have no compensation.


How would a barometer reading change if you went to a higher altitude?

As you go to a higher altitude, the barometer reading would decrease because atmospheric pressure decreases with increasing altitude. This is due to the lower density of air molecules at higher altitudes.


When would the barometer be used?

The most commonly barometer used today would be a Aneroid.

Would it be hot or cold if a barometer was dropping?

A barometer does not measure temperature it measures pressure.


If a mercury barometer were carried up a mountain how would you expect the height of mercury column to change?

As a mercury barometer is taken up a mountain, the height of the mercury column would decrease. This occurs because atmospheric pressure decreases with altitude, leading to less force exerted on the mercury in the barometer. Consequently, the lower atmospheric pressure results in a shorter column of mercury being supported.
