A gas-filled balloon with a volume of 2.10 L at 1.20 atm and 20°C is allowed to rise to the stratosphere (about 30 km above the surface of the Earth), where the temperature and pressure are −23°C and 3.00×10−3 atm, respectively. Calculate the final volume of the balloon. ____ L

V1 = 2.1L V2 =
P1 = 1.2atm P2 = 3*10^-3 atm = 0.003atm
T1 = 200C = 20 + 273 = 293K T2 = -230C = -23+273 = 250K
P1V1/T1 = P2V2/T2
V2 = P1V1T2/T1P2
= 1.2*2.1*250/293*0.003 = 716.72L
final volume of the balloon = 716.72L
