A weather balloon is inflated to a volume of 29.1 L at a pressure of 733 mmHg and a temperature of 24.7 ∘C. The balloon rises in the atmosphere to an altitude where the pressure is 365 mmHg and the temperature is - 14.5 ∘C. Assuming the balloon can freely expand, calculate the volume of the balloon at this altitude.
