If you climed a mountain carrying a mercury barometer,would the level of the mercury column in the glass tube?
of the barometer increase or decrease (compared to the mercury reservoir) as you climb the mountain?Explain
atmospheric pressure decreases with altitude.
this is why passenger jets fly at ~30000 feet. less aerodynamic drag up there.
In general, mercury in the tube adjusts until the weight of the mercury column balances the atmospheric force exerted on the reservoir. high atmospheric pressure places more force on the reservoir, forcing mercury higher in the column.
so, lower atmospheric pressure would place less force on the reservoir.
thus the level of the mercury in the column would decrease as you climbed the mountain.
