A certain flexible weather balloon contains 7.4 L of helium gas. Initially, the balloon is in WP at 8500ft, where the temperatur

<h2>The new volume of the balloon at the top of Pikes Peak is 10.2 L</h2>

Explanation:

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

The combined gas equation is,

$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$

where,

$P_1$ = initial pressure of gas = 577.0 torr

$P_2$ = final pressure of gas = 400 torr

$V_1$ = initial volume of gas = 7.4 L

$V_2$ = final volume of gas = ?

$T_1$ = initial temperature of gas = $20.6^oC=273+20.6=293.6K$

$T_2$ = final temperature of gas = $7.5^oC=273+7.5=280.5K$

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

$\frac{577.0\times 7.4}{293.6K}=\frac{400.0\times V_2}{280.5K}$

$V_2=10.2L$

Thus the new volume of the balloon at the top of Pikes Peak is 10.2 L
