Question: A weather balloon filled with helium gas has a volume of 300 m 3 and pressure 1.4 10 5 Pa at the Earths surface

A weather balloon filled with helium gas has a volume of 300 m³ and pressure 1.4 × 10⁵ Pa at the Earth’s surface (where the temperature is 293 K). The balloon is then released and moves to a high altitude, where the pressure in the balloon is 25,000 Pa and the temperature is 250 K (-23°C). What is the new volume of the balloon?
