Part A A weather balloon has a volume of 890 LL when filled with helium at 9 ∘C∘C at a pressure of 320 Torr. What is the final volume, in liters, of the balloon, where the pressure is 0.23 atmatm and the temperature is -25 ∘C∘C, when nn does not change? Express your answer to two significant figures and include the appropriate units. Part B In 1783, Jacques Charles launched his first balloon filled with hydrogen gas, which he chose because it was lighter than air. The balloon, which had a volume of 31 000 LL at STP, reached an altitude of 1000 mm, where the pressure was 663 mmHgmmHg and the temperature was -3 ∘C∘C.
