A balloon is launched when the temperature is 15 oC and the pressure is 0.918 atm. Its volume is 11.1 L. It rises in the air until the temperature reaches -15 oC and the pressure is 0.0012 atm. What is its new volume?

The new volume is 7,606.96 Liter.

Explanation:

The combined gas equation is,

where,

= initial pressure of gas in the balloon = 0.918 atm

= final pressure of gas in the balloon = 0.0012 atm

= initial volume of gas in the balloon =

= final volume of gas in the balloon = ?

= initial temperature of gas in the balloon =

= final temperature of gas in the balloon =

Now put all the given values in the above equation, we get:

The new volume is 7,606.96 Liter.
