A weаther bаllооn cоntаins [V1] m3 of hydrogen gas at a location at which the temperature is [T1]°C and the pressure is [p1] kPa. The balloon then rises to an altitude where the temperature is [T2]°C and the pressure is [p2] kPa. Assuming the balloon expands freely so that the gas pressure inside always equals the outside pressure, and the hydrogen is in thermal equilibrium with the air, what is the balloon’s new volume in cubic meter? Enter only a numerical value with three significant figures, no units.
