A weather balloon is filled to a volume of 6000 L while it is on the ground, at a pressure of 1 atm and a temperature

of 273 K. The balloon is then released into the atmosphere. As the balloon rises, the pressure decreases to 0.3 atm

and the temperature decreases to 240 K. What is the final volume of the balloon at this temperature and pressure?

Round your answer to the nearest tenth.

17582.4 L

Explanation:

Ideal gas law:

PV = nRT

where P is absolute pressure,

V is volume,

n is number of moles,

R is universal gas constant,

and T is absolute temperature.

Since n is constant:

PV / T = PV / T

(1 atm) (6000 L) / (273 K) = (0.3 atm) V / (240 K)

V = 17582.4 L
