Aweather balloon is inflated to a volume of 28.5 l at a pressure of 748 mmhg and a temperature of 28.0 degrees c. the balloon rises in the atmosphere to an altitude of 25,000 feet, where the pressure is 385 mmhg and the temperature is -15.0 degrees c. assuming the balloon can freely expand, calculate the volume of the balloon at this altitude.

The volume of the balloon at this altitude is 47.46 Liters.

Explanation:

Initial pressure of the gas =

Initial volume of balloon =

Initial temperature of the gas in the balloon =

Moles of gas in balloon = n

...[1]

Moles of gas will remain the same when the temperature pressure and volume conditions are altered.

Final pressure of the gas at given altitude=

Final volume of balloon at given altitude =

Final temperature of the gas in the balloon  at given altitude =

...[2]

From [1] and [2]

The volume of the balloon at this altitude is 47.46 Liters.
