Assume that for every increase in height of 1 m, pressure secreases by 10 mm Hg. Initially, an experimental air ballon of miximum 200 L capacity has 150 L air at 1 atm at sea-level. At what height, the balloon is expected to burst ?

On the surface of the earth at 1 atm pressure, a balloon filled with H_(2) gas occupies 500 ml. This volume 5/6 of its maximum capacity. The balloon is left in air, it starts rising. The height above which the balloon will burst if temperature of the atmosphere remain constant and pressure decreases 1 mm for every 100 cm rise of height is

On the surface of the earth at 1 atm pressure, a balloon filled with H_(2) gas occupies 500mL. This volume is (5)/(6) of its maximum capacity. The balloon is left in air. It starts rising. The height above which the balloon will burst if temperature of the atmospere remains constant and the pressure decreases 1 mm for every 100cm rise of height is:

A balloon containing 1 mole air at 1 atm initially is filled further with air till pressure increases to 4 atm. The intial diameter of the ballon is 1 m and the pressure at each stage is proportional to diameter of the balloon. How many moles of air added to change the pressure from 1 atm to 4 atm.

At sea level, the atmospheric pressure is 76 cm of Hg. If air pressure falls by 10 mm of Hg per 120 m of ascent, what is the height of a hill where the barometer reads 70 cm Hg.

In a mercury barometer, at sea level, the normal pressure of the air (one atmosphere) acting on the mercury in the dish supports a 76 cm column of mercury in a closed tube. If you go up in the air, until the density has fallen to half its sea level value, what height of mercury column would you expect?

The density of air in atmoshpere decreases with height and can be expressed by the relaton rho = rho_0e^(-alphah where rho_0 is the density at sea level , alpha is a constant and h is the height, Calculate the atmospheric pressure at sea level. Assume g to be constatn. The numerical values of constants are : g = 9.8 ms^-2 , rho_0 = 1.3 kg m^-3 , alpha = 1.2 xx 10^-4 m^-1
