Question

The balloon Spirit of Freedom, flown around the world by American Steve Fossett in 2002, contained 550,000 cubic feet of helium. How much PΔV work was done by the balloon on the surrounding atmosphere, assuming atmospheric pressure was 1.00 atm while the balloon was being inflated? Report your answer in both L·atm and in J.

Answer 1

Answer! Given that Volume of Heliche = 550,000 f43 Le lchas that, Ima] - lovol = 35.343 Therefore, 171000 L 35.3 550.000 X 1000 -) 550,000f - 3513 = 1.568107 L system is Now, work done by the Wa-PAV Lal-latm ) (1.56 X6o92) W = -1.56*107 Leatm Now, converting Lath to I = -1.56X60 7 L-ath & 2013 J -) 1.58 X10" T so, The work done is 11.588 109 5] Lath
