Suppose a balloon is filled so that its volume is 2.00 L when the pressure is 750 torr and the temperature is 24°C. What volume will it occupy if it rises to an elevation where the pressure is 375 torr and the temperature is 12°C?
A) 0.261 L
B) 0.500 L
C) 2.00 L
D) 3.84 L

Using the combined gas law: (P1 * V1) / T1 = (P2 * V2) / T2, where temperatures are in Kelvin. Convert temperatures: 24°C = 297K, 12°C = 285K. Solve for V2: V2 = (P1 * V1 * T2) / (P2 * T1) = (750 torr * 2.00 L * 285 K) / (375 torr * 297 K) = 3.84 L.
