A gas-filled weather balloon with a volume of 58.4 L is released at sea-level conditions of 755 torr and 23°C. The balloon can expand to a maximum volume of 831 L. When the balloon rises to an altitude at which the temperature is -5°C and the pressure is 0.075 atm.
a.) Will it reach its maximum volume?
b.) What is the final volume of the balloon in Liters?

Please utilize the ideal gas Law: PV=nRT. For the gas in the weather balloon, you may consider n and R are constant. Therefore:
pv/t = 755*58.4/ 296 = PV/T = (760*0.075)*V/268
and we get new V = 755*58.4*268/ (296*760*0.075) = 700 (L)
The final volume of the balloon is 700 L. Since 700L < 831L, the weather balloon will not reach its maximum volume.
