A certain flexible weather balloon contains 7.4 L of helium gas. Initially, the balloon is in WP at 8500ft, where the temperatur
Free_Kalibri [48]
<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
