Aweather balloon is filled to a volume of 2 liters with helium gas at a pressure of 101 kpa, at a temperature of 22oc. the balloon is released and floats to a height where the pressure is 90 kpa and the air temperature is now 16oc. what is the new volume of the weather balloon?

The new volume of  weather balloon will be 2.2 Liters

Explanation:

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

where,

= initial pressure of gas =  101 kPa

= final pressure of gas = 90 kpa

= initial volume of gas = 2 L

= final volume of gas = ? L

= initial temperature of gas =

= final temperature of gas =

Now put all the given values in the above equation, we get the final pressure of gas.

Therefore, the volume will be 2.2 Liters.

the answer is b ) square root of 5
