If the height of the mercury column is to decrease by 1 cm, what should be the corresponding change in altitude
Answers
Answer:
it is not necessary to move higher in order for the mercury in a barometer to change 1 CM. Changes in local air pressure are a normal part of the weather. Second, Rising up 1,000 meters from ground level will not create the same change in the column of mercury as a change from 20,000 meters to 21,000 meters. The density of the atmosphere is not a constant. A change from 100,000 meters to 101,000 meters will produce almost no change in the column of mercury.
Answer:
At what height does mercury in a barometer drop by 1 cm?
The atmosphere is pressing down on the Earth because of gravity. A barometer is like a scale which weighs the weight of the air compared to the pull of gravity.
There are two variables to consider:
As the elevation of the Earth's surface increases, there will be less air above the Earth at that point, so the pressure will decrease.
The atmosphere of the Earth is in motion. This causes high or low pressures depending on the strength of this motion and its direction.
So to answer the question: First, it is not necessary to move higher in order for the mercury in a barometer to change 1 CM. Changes in local air pressure are a normal part of the weather. Second, Rising up 1,000 meters from ground level will not create the same change in the column of mercury as a change from 20,000 meters to 21,000 meters. The density of the atmosphere is not a constant. A change from 100,000 meters to 101,000 meters will produce almost no change in the column of mercury.
