ivann1987 [24]

Answer:

The new volume is 7,606.96 Liter.

Explanation:

The combined gas equation is,

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

where,

P_1 = initial pressure of gas in the balloon = 0.918 atm

P_2 = final pressure of gas in the balloon = 0.0012 atm

V_1 = initial volume of gas in the balloon = 11.1 L

V_2 = final volume of gas in the balloon = ?

T_1 = initial temperature of gas in the balloon = 15^oC=273+15=288K

T_2 = final temperature of gas in the balloon = -15^oC=273-15=258K

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

\frac{0.918 atm\times 11.1 L}{288 K}=\frac{0.0012 atm\times V_2}{258 K}

V_2=\frac{0.918 atm\times 11.1 L\times 258 K}{288 K\times 0.0012 atm}

V_2=7,606.97 L

The new volume is 7,606.96 Liter.
