1 atmospheric pressure is equal to:
The magnitude of atmospheric pressure is equal to the pressure exerted by a : (a)76 mm tall column of mercury (b) 760 mm tall column of alcohol (c) 76 cm tall column of mercury (d)760 cm tall column of mercury
At sea level, the average atmospheric pressure is equal to 76 cm of Hg.
At sea level , the atmospheric pressure is 76 cm of Hg . If air pressure falls by 10mm of Hg per 120m of ascent, what is the hight of a hill where the barometer reads 70 cm of Hg . State the assumption made by you.
Assumption: atmospheric pressure falls linearly with ascent.
In the experiment given below, if the atmospheric pressure is 76 cm of Hg (h0) and the height is 3 cm, find the pressure of the gas in the tube.
